Bono performs Talking Heads classic at Sao Paolo karaoke bar

Never the predictable sort, Bono and his U2 bandmates celebrated the end of the South American leg of their mammoth 360° Tour at the Morumbi Stadium, Sao Paolo in Brazil over the weekend by popping into a nearby watering hole, Bar Serato for a bit of a sing-song. There and joined by Muse drummer Dom Howard (who were supporting the Irish boys on these South American dates) and footballing legend Ronaldo, Bono gave a spirited rendition of Talking Heads 'Psycho Killer' before the Edge tried his hand at both 'Miss You' and 'Satisfaction' by the Rolling Stones. The 360° Tour was just last week named the highest grossing tour of all time and the boys still have 25 dates of a North American leg to complete before it all wraps up on July 30 in Moncton, Canada.
