An exceprt from an interview by Rosanna Greenstreet at The Guardian:

Rosanna Greenstreet: To whom would you most like to say sorry, and why?

Boy Geroge: Madonna, because I have said far too many vile things about her and all because she invited me to her birthday party and tried to humiliate me by making sure I was not allowed into an area sectioned off for the truly blessed.
