"He really wanted to do it and he was determined to do it," the group's guitarist said following Osbourne's death

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.

Ozzy Osbourne's Black Sabbath bandmates Tony Iommi, Geezer Butler, and Bill Ward paid tribute to the late 'Iron Man' singer after his death at age 76: 'There won't ever be another like him.'
