Black Sabbath guitarist Tony Iommi spoke about his sickness in an interview with Mojo. Tony survived a severe cancer and now looks healthy. In the interview he said:

My illness has changed my life a lot, and my attitude. When I was going through my treatment, I didn’t think I was going to last, I had stage-three lymphoma.

He also mentioned about former drummer of Black Sabbath, Bill Ward. He said:

“I wanted to get things going quick, and Bill wanted to take longer. Bill seemed to feel he was getting a bad deal.

We never dealt with that, we left all that to management. We just wanted to play together and enjoy it. We were playing with Bill for a bit and then he never turned up…

It would have been nicer to have Bill with us but unfortunately it never happened… At some point I wanna call him. I still love him, he’s still my brother, but you have arguments.

To be honest with you, I don’t know what the fuck happened because I don’t do the business side of it. I’m sorry Bill couldn’t work something out, I really am, but I’m really glad we did this tour.”
