I think I was just lucky to be brought up in a very musical family. My two older brothers were, and still are, very musical and very creative, and music was a big part of my life from a very young age, so it is quite natural for me to become involved in music in the way that I did.

I saw Stephen Sondheim's Sweeney Todd, which I thought was a masterpiece. Not that long ago, I listened to Blackstar by David Bowie and thought that was a masterpiece. Those are two incredibly talented people who've left their mark with us.

Chips of plutonium are twinkling in every lung.

In some ways, when you re-envision a song like that ["Never Be Mine"], there's a completely different energy to it each night.

What I've tended to do is to use my own experiences to get into someone else's mind, like in Wuthering Heights.

Music is like comedy in that you can enjoy a very - for want of abetter word - sophisticated classical piece as much as you enjoy something that's very simple pop.

As an artist, you're never happy with anything you do. It's part of the process.
