I got to live out my 11-year-old fantasies - I got to go on stage with Green Day. Billie Joe called my name from the stage. 'Dookie' was the first album I ever bought. I covered the whole of 'Nimrod' and he'd heard it. That was like the 11-year-old girl dreamed.

Excitable, easily distracted, sometimes vacant, prone to gloominess and also extreme euphoria; I can’t be generous with time, but I try to be generous with affection. I’m really lucky to be able to be in some of these situations and it feels really nice to be able to take people along with me for the ride. Oh, and I’m a pain in the ass as well.

Bono told me how to dance in high heels and he also told me about U2's Glastonbury performance and how everything that could have possibly gone wrong went wrong, including him ripping his trousers on stage. I think he was lunging and his trousers ripped! He was telling me how he had to find a new way of performing that didn't involve moving.

I always seem to feel that everything is about to cave in on me. I think that maybe music is my protection from that and in some senses it's an outlet to turn it into something euphoric: embracing the eventual decline.

I'm completely in love with the world but also terrified of it. It creates some overwhelming feelings. Wanting to battle out that joy and fear is part of my music.

I like to keep my issues drawn, it's always darkest before the dawn.

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.
