Geezer Butler honored Ozzy Osbourne with a moving tribute, reflecting on their early days, lifelong bond, and emotional final show in Birmingham.

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.

Tony Iommi, British heavy metal band Black Sabbath’s co-founder and guitarist is of the opinion that his late bandmate Ozzy Osbourne waited to perform at the band’s farewell concert before passing away. Osbourne, who died on July 22, performed at Villa Park in Birmingham, UK, on July 5 with the original members, Iommi, Geezer Butler and Bill Ward.

He might be famous as Guns N' Roses punk bassist, but Duff McKagan has always professed a love for music in many forms, with a longstanding relationship to both Sabbath and Ozzy Osbourne, even playing on the latter's last two albums.

In an emotional essay, Geezer Butler recalled his decades-long friendship with Ozzy Osbourne and Black Sabbath's final rehearsals.
