Rocker Tom Morello is shedding light on Ozzy Osbourne’s final Black Sabbath show. The late metal god’s friend, 61, shared that Osbourne knew Black Sabbath’s Back to the Beginning concert July 5 would be his last performance. The Prince of Darkness died July 22 at 76.

Ozzy Osbourne was aware he was enjoying his final time on stage when he performed with Black Sabbath just weeks before his death at the age of 76, according to organizer and friend Tom Morello.

The Ozzy Osbourne and Black Sabbath farewell concert was a huge success, but maybe not as successful as originally thought.
