hey Junk, when you saw U2 did they play Bad? That has become one of my favorite U2 songs and seems like it would be a great one to play live.
Of the 5 times I've seen them, they played it either at two of those shows. I think they played it every show on thei 2000/2001 tour and about 30-40% of their shows on their 2005/2006 tour.
