Ozzy Osbourne believes that his marriage to Sharon Osbourne allowed him to live for so long

Speaking in the new documentary Ozzy: No Escape From Now, he said: "If it wasn't for Sharon Osbourne, I wouldn't be here now. I would definitely not have the success I have. I wouldn't be sober. I'd be six foot under without a shadow of a doubt.

"Because I didn't drink any less or do any more drugs than any of them, but all the guys I used to do it with, they're all dead, so there must be something I did right in the world. The one thing I did was have my Sharon."

Part of the Paramount+ documentary takes place the day before Black Sabbath's farewell Back to the Beginning concert in Ozzy's home city of Birmingham - which took place just over two weeks before his passing - and the Paranoid rocker explained the nerve he felt before his epic final gig.

He said: "I'm nervous. It's my last hurrah, so it's gonna be pretty emotional for me up there. I just hope I don't think of Sharon when I'm up there, 'cause then the f****** tears will start coming. We've done a lot of miles together, me and my old girl."

Ozzy added: "This is it. This is the last thing, and I've accepted it, you know?"

The Crazy Train artist had suffered from Parkinson's disease for over two decades prior to his death and it has been revealed that he wanted a back-up plan in case he was too sick to perform at Black Sabbath's final show.

In an extract from his posthumous memoir Last Rites, which was published in The Times newspaper, Ozzy wrote: "Three days after we finally got to England I was back in hospital.

"My blood pressure kept me there for eight days, during which I had nothing to do but worry. Because the show kept getting bigger.

"As all these huge names were announced - Guns N' Roses, Metallica, Steven Tyler from Aerosmith - I was like, holy f***, it's gonna be like metal's answer to Live Aid.

"Lying in bed at night I'd be like, I can't go, I can't do this. I kept saying to Sharon, we'd better get a video made 'cos there'll be an empty stage.

"She just looked at me like I was mad. She knows me better than I do. She knew I was just scared."
