Ozzy Osbourne

You may call me old (please do, in fact), but I remember the days when Ozzy Osbourne was known throughout the rock world as a superb showman, front man for one of the most influential metal bands on the planet, and a great vocalist. His wife was a tower of strength as his manager, and was just about the only person who could keep control of Ozzy. They were never out of the pages of Kerrang.

Now, thanks to MTV, Asda adverts and the X-Factor, they are better known as opinionated loud mouths and/or doddering senile old fools who have taken far too many drugs.

It is a great shame that all the fans of their new celebrity status don't know what they are actually famous for - very few of them would know Paranoid, War Pigs or the Randy Rhoads Tribute album, and would probably turn them off if they came on the radio.
