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.

In a conversation, the words can get stuck, I don't know what to say, I get very anxious.

At the beginning of my career I was going through a really weird phase of dressing in boys clothes. I would only wear one American Apparel T-shirt and shorts and brogues the whole year round. Not the same T-shirt, obviously, but one style of American Apparel T-shirt. I think I was going through a tomboy stage.

I try to maintain a healthy dose of daydreaming, to remain sane.

I guess in order to say something to one person, I have to sing it to a couple of thousand. It doesn't make for healthy relationships.

I'm one of those people that is up for most things. When I was offered to sing at the Oscars I was like, 'Yeah, I want to know what that's like!' I'm always curious to know what things are like - as long as you're not compromising who you are.

I'm quite glad I never learned to play the guitar, because I think I'd write songs that were more classically structured. As it is, I've had to create my own way of writing, which isn't typical. Everything's a big crescendo.
