Fans at the most recent U2 show in New York City were treated to a surprise when Jimmy Fallon appeared on stage to sing with the band. Fallon walked onto the stage from the crowd holding a sign that read "Singer with a broken finger." Once he was on stage, he lowered the sign to reveal who he was. What happened after must have been one of the coolest feelings you could ever have.

If you could sing one song on stage with the band who performs it, what would it be? Mine would be either "Thunder Road" by Bruce Springsteen or "All These Things That I've Done" by The Killers.
