Ozzy Osbourne has told the Sunday Mirror that he will be on his best behavior during his performance for the Queen at the Royal Variety Performance later this month, according to Digital Spy."Finally the Prince Of Darkness gets to play for Her Majesty," Ozzy told the Sunday Mirror. "I'm proud to represent my genre of music — and it won't be too loud. I hope it's a great show. "I did meet the Queen before at the Jubilee Concert. It was weird because I had been looking at her face on a stamp for 50-odd years — but I did notice that she has incredible skin." The annual Royal Variety Performance will be held in Cardiff, Wales on November 21. Osbourne, 56, will join an international slate of entertainers that includes Andrea Bocelli and the BLUE MAN GROUP. His wife, Sharon, will reportedly host the show. Osbourne was forced to pull out of last year's concert because he needed to have an emergency operation on his shoulder.
