"It’s very hard to imagine anyone else being in the Beatles. It’s very hard to imagine anyone else being in U2. People tell me that if you go to a U2 show, when we walk out on stage, everybody has the hairs going up in the back of their neck. What we don’t tell everyone is that happens to us, too. And I don’t know why that is. I think it’s chemistry."
- Bono, 2009
