Vertigo Tour in Lisbon

"You know what I envy of you is that my music, and the music of U2 is like, it’s in space somewhere. There is no particular musical roots or heritage that we plug into. In Ireland there is a tradition, but I’ve never plugged into it. It’s like as if we’re caught in space. There’s a few groups now who are caught in space." - Bono to Bob Dylan, 1984
