Osbourne, who couldn’t walk on his own anymore, sat in a black leather chair. He sang five songs solo, and was then accompanied by his former bandmates Tony Iommi, Bill Ward and Geezer Butler for four final Black Sabbath tunes.

It was a fitting farewell for Osbourne, who gained mainstream fame with the band on the back of hits like “Iron Man” and “Paranoid” before going solo in 1980 with the chart-topper “Crazy Train.” The year prior, he was ousted from the very band he’d co-founded amid a years-long struggle with substance abuse.
