Rock 'n' roll is ridiculous. It's absurd. In the past, U2 was trying to duck that. Now we're wrapping our arms around it and giving it a great big kiss.

At the heart of the Irish economy has always been the philosophy of tax competitiveness. On the cranky left, that is very annoying; I can see that.

I put Catholic guilt to work pretty good for a rich rock star.

It's much easier to be successful than it is to be relevant. The tricks won't keep you relevant. Tricks might keep you popular for a while, but in all honesty, I don't know how U2 will stay relevant. I know we've got a future. I know we can fill stadiums. And yet with every record, I think, 'Is this it? Are we still relevant?'

For all that "I was lost, I am found," it is probably more accurate to say, "I was really lost, I'm a little less so at the moment.

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.

Whenever I see grace, I’m moved.
