U2 and Muse officially wrapped up their South American stadium tour on Wednesday night, but hours after the show ended they headed over to the Sao Paulo nightclub Bar Secreto and continued playing on a considerably smaller stage. You'd think anything that happens super late night at Bar Secreto remains a secreto, but thankfully somebody brought a camera and uploaded some of the songs to YouTube.

Click here to watch bits of every song, including The Edge singing "Miss You" and "Let's Dance" and Mullen take a rare turn at the mic with "The Wild Rover." It's unclear if Adam Clayton and the rest of Muse were in the club. Maybe they were playing next door at Bar Super Secreto.
