Pop superstar George Michael blames his marijuana habit for his dreadful memory - he can remember hardly anything from his days in 1980s pop duo Wham!. The FAITH singer admits he is addicted to the drug - and is aware it is slowly ruining his voice - but believes it keeps him creative. Michael says, "It's strange how little I remember from the Wham! days because I was working so much. "I was totally sober at that time and although there were some important experiences, like our tour to China, I can hardly remember anything."
