Black Sabbath retired following an extensive farewell tour from 2016 to 2017. The shows featured three of the band’s four founding members – singer Ozzy Osbourne, guitarist Tony Iommi and bassist Geezer Butler – but not original drummer Bill Ward, who pulled out of the band several years earlier due to a contract dispute.

After Metallica’s performance, Osbourne, 76, came out on stage and performed a five-song set by himself, before he was joined by his former bandmates Tony Iommi, Bill Ward and Geezer Butler for four of the group’s songs.
