Ozzy Osbourne was known for his wild stage persona and outrageous rock star antics, but behind the scenes, he had a heart of gold, according to his longtime Black Sabbath bandmate, Geezer Butler. In an essay for The Sunday Times,

Osbourne, who suffered from advanced Parkinson’s disease, performed at the final concert without any issues. Seated on a bat-winged throne, he sang five solo songs and four Black Sabbath songs, ending his final show of his career with the 1970 classic "Paranoid.”

Black Sabbath guitarist Tony Iommi said he thinks bandmate Ozzy Osbourne was "determined" to play the group's farewell show and "really just held out" to do so weeks before his death.
