9:23 am: Coffee? Check. Cable access in conference room? Check. Sleep-deprived workhorses masochistic enough to to live blog Live Earth? Double check.

9:25 am: Bravo launched their broadcast 30 minutes ago with MTV alums Dave Holmes and Karen Duffy as our moderators. Kennedy must've been unavailable. Shame. So far, we've seen Jack Johnson and Wolfmother rock Sydney, and watched Taking Back Sunday talk up the importance of being green. We're thinking this will be mentioned more than once today.

9:29 am: Reunited rockers Crowded House take the stage in Sydney. "I know you're in good voice 'cause I heard you," frontman Neil Finn says to the crowd, prompting a bevy of hand-sways and an all-for-one singalong to 'Fall at Your Feet.' We got twenty bucks on 'Don't Dream It's Over' as the followup.

9:33 am: Score! Hands back to swaying. Crowd back to singing.

9:39 am: Crowded House suffers a blackout midway through 'Something So Strong.' Finn doesn't mind. It does conserve energy, after all. The band plays on.

9:48 am: We head over to Tokyo, where Linkin Park launch into 'In the End.' Chester Bennington could use a hug, and judging by the amount of sweat, probably some antiperspirant.

9:53 am: LP enjoy conjuring the image of "breaking," both literal and metaphorical, but mostly the latter. The band ends their three-song set with 'Breaking the Habit' and 'One Step Closer,' where we learn that they're about to, well, break. Hot Topic crowd rejoices in fashionable misery.

10:06 am: Dave Holmes is uber-excited to see Rihanna take Tokyo's stage.

10:08 am: Rihanna opens with 'Pon De Replay,' and appears to have ransacked Joan Jett's closet and skeefed her biker gloves. Recycling!

10:19 am: SOS Allstars take the London stage. Celebrity sit-ins: Foo Fighters drummer Taylor Hawkins, Red Hot Chili Peppers drummer Chad Smith and Queen drummer Roger Taylor.

10:22 am: Second reunited band of the day: Genesis with 'Turn It On Again.'

10:30 am: Madonna is too good to remember your name but gives an empowering shout-out with 'Hey You,' a call-to-action tune.

10:41 am: Back to Rihanna, who Holmes loves, yet insists on calling "Ree-hanna," with 'Umbrella.' Ella. Ella. Ey. Ey. Ey.

10:43 am: Umbrellas are a many versatile thing. They can serve as protection from rain, UV rays and function as a makeshift cane. Or, if you're angry at a paparazzi photographer, a weapon.

10:47 am: World debut of Nunatak, five scientists who are part of the British Antarctic Survey's Rothera Research Station. And, as it looks, the only brave souls to perform in Antarctica ... without a crowd. Or stage.

11:04 am: Two words: Worm Poop.

11:06 am: Shakira shakes her bootay for the planet, y'all. The dudes in Hamburg's front row give thanks.

11:21 am: Another MTV alum! Carson Daly interviews Live Earth founder Kevin Wall. Dave Holmes retreats to a corner.

11:24 am: Snow Patrol is 'Chasing Cars' in London. Hope they're hybrid.

11:36 am: VH1's Aamer Haleem chats with Kelly Clarkson backstage in East Rutherford, New Jersey. She supports AFI's vegan schtick but thinks it's "a weird food decision."

11:41 am: Holmes introduces to us, again, Genesis and their 'Land of Confusion.' We get 'Invisible Touch' instead. Someone got punk'd.

11:48 am: Still in London, the Black Eyed Peas take the stage with 'Pump It,' and give shout-outs to Brazil and the U.S.

11:56 am: Before performing her own 'Big Girls Don't Cry,' Fergie assures us that while walking away from bad habits can be hard, it can be done. Britney, take note.

12:08 pm: John Legend follows BEP with 'Ordinary People.'

12:14 pm: AFI tell Aamer Haleem backstage that Al Gore approached the band last year at the MTV Video Music Awards regarding Live Earth, making them the most unlikely BFFs since Bono and Jesse Helms.

12:18 pm: Duran Duran take the London stage, performing the appropriately titled 'Planet Earth' and 'Ordinary World.' No sign of Justin. However, we do learn that DD was Dave Holmes' first concert. Ours? Lilith Fair, Janet Jackson's Rhythm Nation 1814 and Suicide. There will be a quiz on this later.

12:32 pm: DD continue with 'Notorious.' Did JT stand us up?

12:39 pm: Yes. Yes, he did. We blame Jessica Biel. Simon Le Bon and Co. wrap with 'Girls on Film.'

12:51 pm: Genesis finally offer up the previously promised 'Land of Confusion.'

1:01 pm: Daryl Hannah doing what she does best: not acting.

1:06 pm: Red Hot Chili Peppers heat up the London stage with 'Can't Stop.' Yeah, we went there. Chili peppers. Global warming. C'mon!

1:19 pm: Aamer is hanging with Dave Matthews backstage. We have no idea what Matthews is talking about but he's saying "conscious" a lot. He also jokes that Hummer-owning folk should only drive said vehicles on Sundays. What would Jesus do?

1:23 pm: Garth Brooks and wife/fellow country superstar Trisha Yearwood sing 'We Shall Be Free' from the Nation's Capitol on the the world's smallest stage (also in the name of some kind of conservation, we presume). Meanwhile, Brooks' Stetson is taking up most of the room.

1:26 pm: Linkin Park are back. Still angry. Still need hugs.

1:43 pm: Corinne Bailey Rae and John Legend team up for a cover of Marvin Gaye's 'Mercy Mercy Me.' Legend throws in a little 'What's Going On' for good measure.

1:58 pm: RHCP return with 'By the Way.' Or is it 'Otherside'? Maybe 'Californication'? Same difference.

2:03 pm: Harry Potter, er, Keane frontman Tom Chaplin takes the London stage with his newly svelte bod. Bleach the mane and -- BAM! -- you've got Gerard Way.

2:18 pm: Snoop rocks the iciest ice, blingiest bling -- all this on his mic -- in Germany.

2:20 pm: Metallica leave therapy long enough to load London with 'Sad But True.' James Hetfield's chin spinach puts Kirk Hammett's to shame.

2:29 pm: Bravo launches non-stop New York concert coverage (actually at being held at Giants Stadium in East Rutherford, New Jersey) with Kenna.

2:42 pm: While Bravo re-runs Rihanna's 'Umbrella'-ella-ella performance, KT Tunstall and her gold-lame pants are on the NY stage. The non-stop NY coverage, by the way -- not so non-stop.

2:51 pm: Bravo gives us the KT. 'Black Horse and the Cherry Tree' makes a summer comeback one year on, this time with kazoo! Meanwhile Spinal Tap has every able-bodied man in London on stage playing guitar. Among them, Metallica's James Hetfield and Kirk Hammett.

3:05 pm: Duff and Holmes alert us that Al Gore has entered the building in East Rutherford, nearly resulting in their decapitation by Secret Service.

3:18 pm: Long Island screamo troupe Taking Back Sunday -- now on stage at Giants Stadium -- should totally hang out with Linkin Park. After playing Light as a Feather, Stiff as a Board, the two could compare emotional bruises or something.

3:41 pm: Eco enthusiast Leonardo DiCaprio takes the NY stage for one of his many call to actions. "What once seemed like science fiction is now an inconvenient, and undeniable truth," he said of global warming before introducing the man of the hour: Al Gore.

3:44 pm: A denim-clad Gore says his thanks and quickly passes the mic to Keith Urban and Alicia Keys, who team for a rendition of Rolling Stones' 'Gimme Shelter.' Meanwhile, the Pussycat Dolls are on stage in London, singing 'Stick Wit U.'

4:07 pm: Foo Fighters are about to take the stage in London, while Chris Cornell and his soul patch are crooning to Germany right now.

4:12 pm: Model and tsunami survivor Petra Nemcova just gave us some serious perspective; It could be worse than being holed up in a conference room for 16 hours. Like, say, clinging to a palm tree for dear life for eight hours in Southeast Asia.

4:14 pm: Ludacris incites a bevy of rump shaking up in the dirty Jerz. Stadium mom and dads cringe at the onset of 'What's Your Fantasy.' Once more with feeling!

4:39 pm: Dave Holmes gets some face-to-face with R&B diva Alicia Keys backstage. "Bringing people together from different worlds shows that we are one world," she said about her unlikely duet with Keith Urban. Keys takes the stage solo a little later. At the moment, California punks AFI are up with frontman Davey Havok looking mighty purdy in a striped suit. We expect nothing less from a one-time World's Sexiest Vegetarian. Wonder how long it'll be before that jacket comes off.

4:44 pm: Answer: Two minutes and 47 seconds. Approximately.

4:49 pm: Havok waxes poetic about veganism and David Bowie before the band launches into Bowie's 'Ziggy Stardust.'

4:57 pm: AFI hooked up with Al Gore at the VMAs, and Ludacris reveals to Holmes backstage that Gore cornered him at a post-Oscar "rich house party" earlier this year. Lesson learned? Al Gore's got mad game.

5:05 pm: Madonna, her cleavage and a children's choir are singing the official Live Earth anthem, 'Hey You,' on a London stage right now. Joss Stone is up in South Africa.

5:06 pm: Fall Out Boy take the NY stage and bassist Pete Wentz is hoodie-less -- a sure sign of the Apocalypse. The bassist broke uniform with a vest. Tweens swoon.

5:16 pm: Madonna is joined on stage by Gogol Bordello for a flaming rendition of 'La Isla Bonita.'

5:20 pm: FOB close with 'This Ain't a Scene, It's an Arms Race.' Karen Duffy proclaims that henceforth Fall Out Boy shall be known as Fall Out Men.

5:23 pm: Madonna just lost her skirt and wound up in a makeshift go-go cage. All in a day's work.

5:28 pm: Akon takes the NY stage. Hide your daughters.

5:36 pm: Layers of Akon's clothing removed thus far: three. Proclamations of stripper love: one. Fans thrown: zero.

5:41 pm: ALERT! AKON IS IN THE CROWD!

5:42 pm: Rest your heads. He's riding the shoulders of a security guard, high-fivin' every Jack and Jill he passes.

5:46 pm: And we're back to Linkin Park. Again.

5:55 pm: John Mayer is up in Jerz now. At least our moms are happy.

6:02 pm: Mayer brings down the buzz with 'Gravity.' Zing!

6:09 pm: He's 'Waiting on the World to Change.' We're waiting on the performer to change.

6:13 pm: From our mouths to God's ears. Duffy and Holmes try out their own "guitar faces." Look at what you've done, Mayer.

6:15 pm: Shakira's belly button is back for an encore, y'all! Mountains sold separately.

6:24 pm: Melissa Etheridge and her roundback 12-string take the stage in Jersey. She launches into a new song, 'Imagine That,' and breaks midway to rant about a young, eigth grade Melissa, criminal presidents, a lost America, flying cars that never came to pass, credit cards and unjust wars. Yeah, we don't know either.

6:36 pm: Yet another new song, 'What Happens Tomorrow,' also interrupted by a good preachin' -- this one about differing alcoholic preferences, the American Dream and worldwide citizenship as granted by U.S. birth. For the record, Etheridge is a beer gal, not wine. That we caught.

6:42 pm: Melissa Etheridge is officially the Rosie O'Donnell of Live Earth.

6:45 pm: Yes, Melissa, to answer you're question: We're awake and we're scared ... of you. LYLAS!

6:50 pm: Al Gore rescues us returns to the stage, asking folks to take the seven-point pledge of Live Earth.

6:52 pm: Cut to London and the Foo Fighters. A Jesus-lookin' Dave Grohl leads a semi-solo, plugged 'Everlong.'

7:01 pm: Randy Jackson introduces "the one and only" Alicia Keys, who opens with the O'Jays' 'For the Love of Money.'

7:08 pm: There really is only one ecologically-minded R&B song! And now, we've heard it twice. Keys sits at her baby grand and croons 'Mercy Mercy Me.'

7:12 pm: Done with covers, Keys debuts a new song, 'The Thing About Love,' telling the crowd, "I want you to feel this. This is just for you tonight."

7:22 pm: Bravo takes us across the pond to our long-desired Madonna footage. Holy cleavage, Batman!

7:30 pm: Dave Matthews Band takes the stage at Giants Stadium. What's that smell?

7:40 pm: DMB rips into 'Don't Drink the Water.' Alanis Morissette isn't present to sing her original backing vocals. Perhaps she had a previous engagement to spend more beach time with Matthew McConaughey.

7:57 pm: Madonna's back with a strap on ... guitar, that is. 'Ray of Light' simultaneously rocks and raves.

8:07 pm: Texan Kelly Clarkson takes the stage, y'all. The quasi punked-out singer opens her NY set with 'Walk Away.' Got that, Clive?

8:14 pm: Clarkson offers up a trifecta of new tunes ('How I Feel,' 'Never Again' and 'Sober'), admires the stage decor (tires, y'all!) and kisses off with 'Since U've Been Gone.'

8:27 pm: Back to the Red Hot Chili Peppers in London. Different song. Same melody.

8:36 pm: Kanye West is in the NY house! The rapper opens his set with 'Heard 'Em Say,' followed by 'All Falls Down' and 'Gold Digger.'

8:46 pm: 'Diamonds From Sierra Leone' rears its head. We are reminded of a Fiona Apple lyric from her own 'Red Red Red': "I don't understand about diamonds/And why men buy them/What's so impressive about a diamond/Except the mining?" Word association, people.

8:51 pm: West won't stop -- we get 'Jesus Walks' and 'Touch the Sky.' From our greed to yours.

8:54 pm: Karen Duffy talks "knockers" with Jon Bon Jovi.

8:55 pm: Beastie Boys rock London with 'Sabotage,' looking a helluva lot like the Blues Brothers.

9:03 pm: Cameron Diaz's teleprompter skills leave something to be desired. Once more, Al Gore to the rescue! Together, they introduce Jersey's own Bon Jovi.

9:09 pm:The crowd is eating this ish up. 'It's My Life' prompts more fist pounding than Ike Turner.

9:12 pm: Guest blogger Phil Spector: "This show kills!"

9:14 pm: "Will you please rise for the playing of our national anthem?" Jovi asks the crowd as the band launches into 'Dead or Alive.' Francis Scott Key (R.I.P.) is so pissed right now.

9:20 pm: Bon Jovi asks, 'Who Says You Can't Go Home?' Answer: Our editor, since we still have forthcoming sets from Smashing Pumpkins, Roger Waters and the Police.

9:41 pm: And now, what we've all been waiting for: the Smashing Pumpkins.

9:47 pm: Billy Corgan scratches out a jagged take on 'The Star Spangled Banner' during new tune, 'United States.'

9:49 pm: Bravo cuts to commercial. Oh no they di'n't!

9:51 pm: OK, back. Corgan and Co. wax nostalgic by tearing into 'Bullet With Butterfly Wings.'

9:55 pm: Corgan says his Pumpkins would like to play their latest single, 'Tarantula,' which he pronounces "Tar-an-too-la."

10:00 pm: "Our new album, 'Zeitgeist,' comes out Tuesday," Corgan said from the stage. "We know you'll all buy it and not illegally download it like you did the rest of our albums." The frontman saved face by adding, "Just kidding," before closing the band's set with 'Today.'

10:05 pm: 50 percent of your Spinner live bloggers would make out with Billy Corgan. Hint: One of them isn't the person who name-checked Fiona Apple and Alanis Morissette.

10:13 pm: A Genesis rerun. That 'Invisible Touch'? Yep, she still has it.

10:22 pm: Pink Floyd's Roger Waters takes the NY stage and gives the crowd some 'Money.'

10:27 pm: 'Us and Them' shows up, making us long for those mind-expanding college days of yore. Or at least Live 8.

10:35 pm: Five bucks says Karen Duffy calls this performance "groovy."

10:38 pm: A choir of Jersey schoolkids wearing "2Gether We Stand" T-shirts join in on the set-closing 'Happiest Days of Our Lives/Another Brick in the Wall Part 2,' while an inflatable pig that reads "Together We Stand, Divided We Fall," floats overhead. On the flipside? "Save Our Sausage."

10:46 pm: On to Rio De Janiero, where Lenny Kravitz gets heads bopping with 'Are You Gonna Go My Way?'

10:51 pm: Funny, we were just thinking that a little 'Red, Red Wine' would be just the thing to help us make it through to the Police. The Live Earth gods are listening. Wait ... maybe we should've been more specific.

10:56 pm: Bravo keeps giving us sloppy seconds. Up now: Duran Duran, 'Girls on Film.'

11:02 pm: To borrow from Dave Holmes -- and this will be the only time we ever do such a thing -- the time has come for the proverbial cherry to placed atop this day. Ladies and gentleman, the Police. Stewart Copeland and his sweet headband launch us into 'Driven to Tears,' a sentiment we echo after 14 hours of blogging.

11:08 pm: 'Roxanne' = the most popular hooker ever. We choose to ignore Julia Roberts.

11:11 pm: SPOILER ALERT: Kanye West joins the Police on 'Message in a Bottle.' NBC just aired the footage. Bravo kicks themselves in the arse.

11:22 pm: Told you so. Added bonus (?): John Mayer on guitar.

11:29 pm: Apparently that was the grand finale. What, Springsteen wasn't available? It was in his backyard. Meanwhile, Al Gore sends us all off with a hearty thanks.

11:31 pm: To recap: It was a day of reunions (Crowded House, Genesis, the Police), odd couples (Keith Urban and Alicia Keys), soapboxes (Melissa Etheridge, AFI) and resurrections (Smashing Pumpkins, Marvin Gaye) -- all in the name of environmental awareness. The musicians, actors/actresses and politicians have done their part, now do yours. Go to www.liveearth.org to find out how you can get involved.
