Following the departure of Vinny Appice and Ronnie James Dio in 1982 to form their own band (Dio), Geezer Butler and Tony Iommi found themselves at a dead end. Who better to bail them out than the frontman of an equally legendary band - Deep Purple's Ian Gillan.
After a night of drinking together, Gillan agreed to work with them on the Born Again album. Bill Ward returned to play on it too but was unable to tour due to his ongoing battle with the bottle. The resulting album was only released under the Sabbath name after record company pressure and is a metal Marmite release for fans - it also marked the beginning of Sabbath's dark age of revolving lineups.
But it wasn't all bad news, the Born Again tour gave birth to the notorious Stonehenge incident. In a genuine coincidence - Christopher Guest and co. had already included the 'henge idea in a 1982 pilot - what happened to Sabbath was very similar to a scene in 1984 mockumentary, This Is Spinal Tap
While the movie featured a mix up between feet and inches resulting in a hilariously small Stonehenge stage-set, Sabbath's set was too big due to a mix up between meters and feet. The 45-foot high stones were too large to fit into venues on the tour.
Why did Sabbath want a Stonehenge stage-set in the first place? Because of the song of the same name on Born Again.
