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.

The co-founders of Black Sabbath paid tribute to their doomsayer-in-chief following the news of Ozzy Osbourne’s death at age 76 on Tuesday.

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.
