The reunion that few were expecting came in 1985 with Ozzy, looking alarmingly like Pat Butcher, briefly back on stage with his Aston friends for the Philadelphia leg of Live Aid.
Like all the other acts at the JFK Stadium that day, Sabbath only got 15 minutes to play, and burned through crowd-pleasers Iron Man and Paranoid. Plans were afoot behind the scenes to make the reunion long-term but legal issues between Sabbath manager Don Arden and his daughter, and Ozzy's manager, Sharon Osbourne became insurmountable.
It was back to the drawing board for Tony Iommi as he mulled over the future of Sabbath sans Ozzy or Ronnie. It would be 12 years before the famous four would play together again.
