You Oughta Know is your weekly introduction to a wide range of new Canadian artists who are either about to blow up ... or really oughta.

The Internet long ago changed the music industry's star-making machinery, but perhaps nobody has benefitted by the new bottom-up food chain quite as much as Toronto rapper Drake.

He's hardly an undiscovered nobody, having spent eight years as wheelchair-bound shooting victim (and, of course, aspiring rapper) Jimmy Brooks on the cult-smash TV series 'Degrassi: The Next Generation.' But over the past few months, 22-year-old Aubrey "Drake" Graham has ascended to the top of the hip-hop mountain -- including entering the Billboard charts with top ten hits with 'Best I Ever Had' and the Young Money posse cut 'Every Girl' -- without so much as a record deal, much less a commercial album release.

Now that the reportedly $2 million major label bidding war for his debut album has finally ended (he just signed with Lil Wayne's Universal-distributed Young Money imprint) Drake is poised to become not just Canada's biggest-ever rapper, but the biggest rap star of 2009 -- from anywhere.

A seemingly impossible feat, even without the 'Degrassi' baggage.

On This Date in 1976: Jerry Lee Lewis is arrested outside the gates of Graceland, where he was found waving around a gun and demanding to see Elvis Presley.

The Almanac Advises for November 23: "Many of the musical rivalries reported in the press are merely staged events concocted to drum up publicity. In truth, these so-called adversaries are often actually good friends."

On This Date in 1970: Jerry Lee Lewis and his wife (and cousin), Myra Gale Brown Lewis, are granted a divorce. Myra, 13 years old at the time of her wedding, had been married to her 12-years-older husband for half her life.

The Almanac Advises for November 18: "In some families, an older sibling or relative will take on the roles and responsibilities of a parent in the younger relation's eyes. This can especially be prevalent when there is an appreciable age difference between the family members."

On This Date in 1957: Jerry Lee Lewis makes his television debut, performing 'Whole Lotta Shakin' Going On' on 'The Steve Allen Show.'

The Almanac Advises for July 28: "Simply known as hyperactive behavior, ADHD -- or Attention Deficit Hyperactivity Disorder -- affects one in every 20 people, mostly males. It is thought that seven out of 10 children with the disorder maintain it throughout adulthood."

Proving they can still rock, legends John Fogerty, Jerry Lee Lewis and Little Richard took the stage at the Grammy Awards for a medley of classic favorites. The 'Cornerstone of Rock' montage was opened by the 62-year-old Fogerty -- his first time ever to perform at the Grammys. The 72-year-old Lewis was next, tickling the ivories on his classic 'Great Balls of Fire.' Then the cameras panned to another piano, where the 75-year-old Little Richard electrified the crowd with 'Good Golly, Miss Molly.' Fogerty's band backed all three players.

The celebration of the 50th Grammy Awards kicked off in L.A. last night with the Music Preservation Project, a night dedicated to 'Songs of Change.' And the hour-and-a-half show -- a mix of live performances, video footage and speakers -- did an impressive job encompassing five decades of musical social commentary. Of course it helps when you have the likes of Jerry Lee Lewis and John Fogerty.

After Ryan Shaw started the night off with Sam Cooke's 'A Change is Gonna Come,' Lewis was brought out to a standing ovation. He left to another standing o following a raucous 'Great Balls of Fire,' which he said he was doing by request. Meanwhile, Grammy nominee Fogerty -- a voice for social change with Creedence Clearweater Revival and on his own -- delivered a powerful four-song set that started off with a moving acoustic 'Deja Vu All Over Again,' accompained by a poignant video of war footage and the effects on survivors.

Fogerty, who performs on Sunday's show with Lewis and Little Richard, told a story of how his mom used to take him to see the folk singers and meeting Pete Seeger when he was just 12, and the effect that had on him in terms of combining "the beat" with a message. To illustrate, he then ripped through a 'Fortunate Son' that had the crowd in a frenzy.

On This Date in 1986: The first group of inductees to the Rock and Roll Hall of Fame -- Buddy Holly, Chuck Berry, Elvis Presley, Fats Domino, James Brown, Jerry Lee Lewis, Little Richard, Ray Charles, Sam Cooke and the Everly Brothers -- is officially accepted.

The Almanac Advises for January 23: "Upon being presented to and taking leave of royalty, it is customary for men to bow and women to curtsy. Address royalty as 'Your Majesty' or 'Your Royal Highness' at first, and from then on as 'sir' or 'ma'am.' Speak only when spoken to."
