Seriously, ur not going to include Tony Martin, Glenn Hughes or Ian or Ray Gillen. What kind of Sabbath fan are you?! Only teasing. For me it's all Ozzy. I honestly dont know why they didnt have enough integrity to just change the name of the band. Their style was much different with Dio, and Dio hated singing Ozzy's songs. I saw them at the Roseland in '94 with Tony Martin singing and it was horrifying, to say the least. Tony introduced himself to the audience and then pointed behind to Tony, Geezer and Vinny and said 'I think you know who these guys are' and then they went into the next song. It's ok, I was there to see Motorhead who played earlier in the evening.
