Ozzy: "The doctor can fuck himself"

Black Sabbath returned to OzzFest on Thursday, August 4th, after missing several dates due to an ailing Ozzy Osbourne. The group did their full headlining set at the DTE Energy Music Theatre in Clarkston, Michigan, with Osbourne warning the crowd early on, "If my voice breaks up from time to time, it's not my fault. I'm sick, as you know, but I told the doctor to go fuck himself. I'm doing the best I can, babes."

Black Sabbath missed shows in Holmdel, New Jersey, on July 27th; Noblesville, Indiana, on Sunday (July 31st); and Columbus, Ohio, on Tuesday (August 2nd).

Ozzy's voice was noticeably rough, though he was in otherwise energetic form, mooning the audience at the start of the show, tossing a bucket of water on the front rows later on, and jumping around throughout.

Specific details about Osbourne's ailment have not been revealed, but sources told us it's primarily a throat problem.

OzzFest continues on Saturday, August 6th, in East Troy, Wisconsin. However, Sunday's show in Somerset, Wisconsin, has already been rescheduled to September 10th, to give Ozzy a day off to rest his voice.
