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.

And if I had to spend 20 years in the band just to play that show, I think it would have been worthwhile.

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.

I don't think anybody could imagine the life that I've been lucky enough to have. It's been an incredible journey.

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.
