Black Sabbath including front man Ozzy Osbourne are set to appear in an hour long special of the hit US show CSI.

In the episode, which will air in the UK later this year, the band apparently get caught up in a series of gruesome murders.

Members of the regular cast have commented on how easy the band was to work with, much to their surprise.

“I expected them to want to bite everyone’s head off but they were a real joy to work with – more like bats out of heaven than hell,” said Ted Danson, one of the show’s stars.

Ozzy and bassist Geezer Butler even managed to get themselves speaking roles in the episode and will premiering their comeback single entitled End Of The Beginning during the episode.

Black Sabbath reformed last year to play their first concert together since 2005 but caused a stir after using Tommy Clufetos as a drummer instead of Bill Ward who was an original member of the band.

Ozzy claimed that the snub was due to the fact that Ward didn’t know what he was doing anymore telling Mojo magazine: "You know them yellow f**king stick-on memo notes? He had them all over his f**king drums. I was like, 'What the f**k's that for, Bill?' He said, 'I can't remember what I'm doing.' I go, 'How are you gonna remember out of those 500,000 bits of paper stuck all over your kit, which one you're looking at, Bill?’”
