If Bono left, we could carry on. If I left, we'd be screwed.

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

I joined a band to hit things.

The only thing I wouldn't like to do is to play roles as a musician. I'm not sure that I would be comfortable doing that, and I'm not sure I'd be very good at it. I think I would be better served, and would be a better partner, if I was in something outside of myself.

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.

When you're in the music business, everything is very personal, because you are invested in everything there's a very deep, personal attachment to your music.

People say, 'Why don't you do interviews? What do you think about this? What do you think about that?' My job in the band is to play drums, to get up on stage and hold the band together. That's what I do. At the end of the day that's all that's important. Everything else is irrelevant.

Unfortunately, as far as the music is concerned, what defines relevance is whether you are on the radio or whether you are on the cover of a magazine or whether you're winning MTV awards, and so on and so forth.

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.

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.

It's a tough life being a pop star. You know, at the end of the day when you've paid all the bills and put the kids through college and that, you know, there's only enough left for a small island off the South Pacific.

I will never be a career actor, I don't think. I don't feel that I have the skill set to jump into it that way, although I wouldn't mind giving it a try.

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

The longer you've been acting, normally, the better you are at it. As a musician, it doesn't work like that.
