I'm a fan (and you should be too) because...First CD i brought was Down to Earth and it was awesome and is still a regular on my MP3. There is no one like Ozzy the guy's just a genious and a legend on and off stage and no matter how successful he is he's still got his Brummie accent and he's still a down to earth guy. He isn't a complete faker as most superstars are these days pretending to be something they are not and you gotta have complete respect for the guy on this basis.
I thought I was a late starter listening to the Down to Earth CD but unknown to me I'd been brought up on Black Sabbeth by my step dad and had been listening to Ozzy for years with out realising it.
