Tony Iommi has spoken publicly for the first time since Ozzy Osbourne’s passing, and said he believes the singer was committed to putting everything he had left into Black Sabbath’s final show, even if it would be the death of him.

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.
