Bono 1987, at a Joshua Tree rehearsal

"I think every time I go back to past events, you know the facts reinforce the fact that we always turn out to be a better band than I think we are. And I guess you know that's sort of a good surprise to have as a band. We work together and try and push out the envelope, because we have a sort of band dysmorphia as regards to the quality of what we're doing. We're always trying to break through that." - Adam, 2020
