Rock stars are good at making noise.

Perspective is the cure for depression.

There was a moment when Prince did rock & roll with a sponge-y seductive sound. I think that's what was in our head for 'Get On Your Boots.' But actually, the song is much more punk rock.

U2's best work has always been when we didn't know what we're doing.

But more than anything else, for the British folks Irish people were all terrorists. So when we went to Britain, it was always a lot of resistance to U2. And that's why we came to America.

The great music for so many artists - the Beatles, the Rolling Stones - was always at the moment when they were closest to pop. It would be easy for U2 to go off and have a concept album, but I want us to stay in the pop fray.

God is in the slums, in the cardboard boxes where the poor play house. God is in the silence of a mother who has infected her child with a virus that will end both their lives. God is in the cries heard under the rubble of war. God is in the debris of wasted opportunity and lives, and God is with us if we are with them.
