I have this sensation of being in flight all the time, but being on stage is like creating a sanctuary in which you can completely lose yourself. The bits of your personality that you keep under wraps in ordinary life, you can let them run free.

A lot of the songs on the new album are about imaginary things, things that you can't touch - ghosts and rumors, my dead grandmother, things visiting you in a dream.

I can't just have one painting - I need to cover the wall in paintings. It's the same with my music. I want to mix everything together to create more.

The stage is a place where I can be wholly myself. Even though you're in front of people almost to be judged, it is a place without judgement.

I think I should get a bigger between-the-song persona, so then I'm not wandering around the stage like some mad old auntie that's saying hello to people and falling over.

When you're dressed up as David Bowie, with your eyebrows completely bleached, and you're doing this kind of strange dance with Paul McCartney while singing "Rebel Rebel" in the middle of the Met ball, and Madonna's looking at you . . . I was just thinking, It's become a bit weird.

If you do something with your whole heart and it's a mistake, you can live with that.
