Muse and U2 Appear Live Together in Brazilian Bar

Local drinkers in Sao Paulo's intimate Bar Secreto were left stunned last week as members of U2 and Muse turned up at the bar, fresh from finishing the South American leg of U2's '360' World Tour, and began to play live.

The groups had been playing at the city gigantic Morumbi Stadium for three nights as part of a seven gig South American stint, and evidently had decided on a late night encore as U2 front man Bono and drummer Larry Mullen took to the stage at the bar. The hastily constructed supergroup was then completed by Muse's Dom Howard for a cover of Talking Heads' 'Psycho Killer (reports The Sun.)'

Muse lead singer Matt Bellamy wasn't in attendance so it was left to the Edge to take up vocal duties on subsequent versions of David Bowie's 'Let's Dance' and the Rolling Stones 'Miss You.' The Irish guitarist of course has history of joining Muse on stage, appearing with the band during their 2010 Glastonbury headlining slot to perform his own group's 'Where the Streets Have No Name.'

U2 now have a break until May 11 when they begin a North American stint with supports including Snow Patrol, the Fray and Lenny Kravitz. It's already been announced that the tour has taken the biggest-grossing amount ever, and will be expected to clear £427m ($695m) by the time it finishes on July 30.

Muse play three dates in Russia and the Ukraine in May before headlining Leeds and Reading Festivals on Aug. 26 to 28.
