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 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.

You live and you learn.

What I really like seeing from the stage is people having their own moments, when people are doing some performance of their own.

'Dog Days' was recorded with pens and the wall, and half a stolen drum kit that was out of tune, in what was basically a cupboard. The only instrument I could really play was my voice, so we just layered everything a hundred times. It was enthusiasm over skill.

When something really hits me, it makes me want to either jump off something really high or lie down and be buried. I want people to get hit and caught by my music.

It's always darkness before the dawn.
