Relevance, for me, is about being creative and doing things that you believe in, whether that's music or acting or painting a picture, or whatever that is.

The big issue with rock stars becoming actors is that sometimes it's not believable, and vice versa with actors becoming rock stars. Sometimes just doesn't fit.

There's a thin line between interesting music and self-indulgence. We crossed it on the Passengers record.

Then Bono arrived, and he meant to play the guitar, but he couldn't play very well, so he started to sing. He couldn't do that either. But he was such a charismatic character that he was in the band anyway, as soon as he arrived. I was in charge for the first five minutes, but as soon as Bono got there, I was out of a job.

It doesn't matter what songs we sing. I'm a drummer. Chicks dig me.

I think I look cool. I don't know about the other three but I look cool, I am cool.

Relevance is a big, big question. It's more about what's your definition of being relevant. In the music world, agism is a big issue. It's about youth and youth culture. There's no other art form that I know that requires you to be a certain age.
