U2 in Berlin

"The essence of what it is to be in a rock 'n roll band to me, now, is just that three-and-a-half minutes. Not giving interviews, not being on television, not all that goes with it. What has drowned out the sound of the rock 'n roll circus has just been the rock 'n roll song. Just that one thing. That's the most existing thing for me." - Bono, 1989
