Capitol Records were very keen for me to write and see how I got on; I think that is what defined my sound. The first session I had was with two young up-and-coming writers, Nick Atkinson and Tom Wilding, and I went into a session a bit nervous because I hadn't written that many songs before.

My kids are Irish; I want them to grow up playing Gaelic football and learning Irish.

I have three children to take care; I have a wife. My job is to take care of them, and I can say it's a pretty cool job to have.

Every year, we couldn't believe it, and even when I look back on it now, to sell 14 million singles, 50 million albums and sell out arenas and stadiums, what Westlife achieved was crazy. It's like One Direction probably don't realise how big they are. They'll look back one day and think, 'Holy God, that was pretty amazing.'

I'd love to act more. I've had to turn down multiple movies because I was on tour, but it's encouraging to know that someday there might be the right role, the right timing. And I've been writing a lot of music, so hopefully very soon I'll have recorded a project of my own. I also want to get a boat and open a restaurant.

I think the benefit of being a writer is that I'm looking for the subtext on the page, because all good writing has subtext. And as a writer, you look at the big scope of things, the big story, rather than just your individual story line, because I think it's important to know what you're in and how you fit into it.

A film maker's energy and creativity don't have to end when he turns over his film.

Ah, the creative process is the same secret in science as it is in art. They are all the same absolutely.
