At a warm-up show at the Lower East Side's Living Room for his forthcoming solo album Rhythm and Repose, Glen Hansard (Swell Season, The Frames, Once) pulled one of the audience members up on stage to sing the Irish ballad "The Auld Triangle." Of course that person was Bono. It was a good decision by Hansard. Not only is Bono one of the most famous rock frontmen of all time, but U2 has covered the song in the past. But we're guessing Bono's never sang it in a sit-down club on Ludlow Street that houses roughly 100 people.
