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.

Where's my heart at? Aw. Um, in my chest. I think it's in there - on the right hand side. Sometimes it's in my mouth and sometimes I can feel it in my stomach, when I get really nervous. So it's pretty physical.

The music is so euphoric,as a way of battling the words. It’s like an exorcism, beating it out with drums, shake this demon out, it’s so visceral because the melancholy has to be drummed out. I can’t let it sit inside me.

Being heartbroken is like having this really horrible freedom. You can be selfish with your thoughts, which can lead to manic creativity, but at the same time you're just really miserable.

For someone so conflicted, who am I to give advice to anybody? It’s such a funny, grandiose idea

I'm obsessed with choirs, and always have been, because of that sense of overwhelming vocals.

It's very flattering when you look into the crowd and people have made an effort and dressed in your style.
