I wore makeup when I was at school, and I wore makeup when glam started. I started wearing it again when punk started. I've always been drawn to wearing it. It's partly ritualistic, partly theatrical and partly just because I think I look better with it on.
I've discovered special makeup by a company called M.A.C. You could wear it on the surface of the sun and it wouldn't move.
Perhaps not as badly applied and not as obvious, but for thousands of years, people have worn makeup on stage.
Whenever I'm home, I haven't got any makeup on. But even in the studio, before I do vocals, I put makeup on.
