I think Mofo is a little bit too techno for U2 these days. Maybe if they got rid of all of the loops and synths and just played it as a band, y'know, and no back tracks for keyboards and drums. Just Larry, Adam, Edge, and Bono. Then I could see it happen.
Well U2 often changes their songs to make them right for the tour.
So during that tour i'm sure Mofo would sound different just as the The Fly during Elevation Tour.
What about Discotheque----wanna hear 60 thousand people shouting BOOM Cha OOM cha Discotheque
