Black Sabbath legends Ozzy Osbourne and guitarist Tony Iommi surprised their hometown crowd in Birmingham, England with a brief performance at the city’s Commonwealth Games. The pair took to the stage as Ozzy shouted out: “I am iron man,” before they launched into Sabbath’s signature 1970 tune, “Paranoid.”

Appearing with the duo were a pair of musicians who had backed Sabbath on their last tour — bassist/keyboardist Adam Wakeman and drummer Tommy Clufetos.

Rolling Stone reported, “Iommi had opened the Commonwealth Games, which include swimming, a triathlon, boxing, and rugby sevens, among other sports, on July 28th, playing a song called ‘Hear My Voice’ with London-born saxophonist and rapper Soweto Kinch. The track featured Iommi’s bluesy guitar solos over new age strings and Kinch’s saxophone lines.”
