Osbourne, who battled Parkinson’s before his death, sat onstage in a black leather chair as he performed for the 42,000-person crowd. He sang five songs by himself, before he was joined by his former bandmates for four Black Sabbath songs.

Days after Osbourne’s death, Kelly shared a clip from his three-season reality series, Jack and Ozzy’s World Detour, to her Instagram Story. “One of the best Ozzy moments ever!” she wrote above the video.
