This is a pretty good interview with Michael from 2007. He talks about his life and his favorite records.
He said something interesting. The interviewer asked if his stage persona of "George Michael" was an act and an invention, and he said something like, "Well, at first I thought it was. But I realized later that everything you do, including the lies you tell, are actually you. After all, this persona is what I wanted people to think I was."
