I think "waste of your brain" is something that my mother would say to me occasionally - I think it's usually when I'm telling her something like that I can remember every outfit I've ever worn.

I quite like the drama of an encore. I think an encore is for those artists who are inclined to do dramatic gestures, and I certainly would say I am inclined towards them.

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.

I'm a choir girl gone horribly, desperately wrong.

The release of 'Lungs' was so hard. It was terrifying, because it was the first time doing everything. The first experiences of media exposure were almost paralysing. I spent a lot of time crying on the floor of the studio - it sent me a bit mad.

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

All the words are already there when you're singing onstage, it's fantastic. You can lose yourself in what you've created. You're controlling this freedom.
