For me, what makes great actors, always is how truthful they are to the character and the story and the emotion that they're trying to tell.

Sometimes the songs you think will be best don't turn out to be best.

I like people like Ani DiFranco, a band called Elbow, of course John Lennon, George Harrison, Barry White. I have a lot of different influences and hopefully they all come together and make some sense.

To play one of the main characters in it, it's not the kind of thing you don't do. Oh, I'd rather not play Pippin in Lord of the Rings... In fact, I'm trying to think - what else would you rather do, you know? I can't actually think of another job that I'd rather do.

But you talk to most filmmakers and it is six, seven, eight years trying to get things off the ground. It is incredible really.

In fact, Russell Crowe once phoned me up to see if I wanted to go to a party but I had to bring my guitar and perform Oh Jean.

The club thing is a world people can associate with, letting your hair down at the weekend.
