Everything has such order and everyone is so focused on doing what they're doing that no one ever pays attention to you spinning and dancing around supermarkets. It's something you find in places like supermarkets and airports, where everything is really ordered. There's something about those places that makes you feel really anonymous.

I feel things in quite an intense way. I'm not actually the most intense person.

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.

Worst nightmares can also appear with your eyes open.

My style of playing is more enthusiasm and instinct than skill.

I started off singing in church as a child. The sound of voices coming together, that was my first moment of touching something outside of myself.

The aesthetic came along the way, I think - just through experimenting, and going on tour, and trying stuff out on stage, having fun with it, and not taking it too seriously. If I had a ballgown at home, I'd wear it onstage. If I found something in a charity shop, I'd wear it. That's where it grew from - just wanting to play dress-up.
