I love that sense of release as you throw yourself into the crowd as hundreds of arms are carrying you.

When you're dressed up as David Bowie, with your eyebrows completely bleached, and you're doing this kind of strange dance with Paul McCartney while singing "Rebel Rebel" in the middle of the Met ball, and Madonna's looking at you . . . I was just thinking, It's become a bit weird.

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.

But I was always much more interested in reading fashion magazines than I was music magazines when I was a teenager. Just that sense of romanticism and escapism and the dream of it has always been quite alluring to me, as well as that sense of becoming a character through clothes.

When I'm singing I'm always trying to get to the highest point possible. I'd fly to the top of Buckingham Palace to sing to the queen.

You live and you learn.
