U2 in Minneapolis

"I can understand why people might be a little fed up with our face. We've been around a while and we probably should've done a decent thing. At least one of us should have ended up in a gutter or collectively, doing something dramatic and mythological like dying in a plane crash. But we're still here and as long as we continue to surprise ourselves. It's worth sharing that with our audience. The moment that stops we're out of here. I'd like to avoid the plane crash thing but I think we might know when to stop." - Bono on what's left for U2, 2014
