This according to Joe Siegler administror

"Sharon does not have any control over Black Sabbath. Tony Iommi owns "Black Sabbath". Period. End of story. There is nothing to discuss in that regard. Tony owns it. He has since the mid 80's when he bought all the rights from the other Sabs. The only "control" Sharon had was Ozzy. If someone did something she didn't like, she could take her Ozzy and go home. No matter what the name, since Black Sabbath appears to be progressing forward without Ozzy, there's jack shit that Sharon can say or do - this stuff should cease to be discussed. The reason it still is being done is because people don't know any better keep going on about it. STOP!"
