Rocker Ozzy Osbourne has fulfilled a lifelong ambition and written a musical - about the Russian mystic RASPUTIN.

The Black Sabbath frontman was inspired to write the unlikely script after watching a BBC documentary about the womanising Romanov hellraiser, whom Osbourne considers a spiritual ancestor.

He says, "It's a major achievement for me, because I've always wanted to do it.

"He's like the original rock star, you know? I said to myself, 'What better thing to write about?'

"I always wanted to do a musical for the West End or Broadway. If it gets picked up it gets picked up, but it was a lot of fun to do anyway.

"Being Ozzy Osbourne is great, but if I don't sing about the f**king devil or bats or whatever, people don't really want to know."

But Osbourne has dashed hopes he'd consider a starring role in the theatre production: "If there is an album I'll sing the part, but I don't want to go on Broadway."
