The bootleg gave themself a second title: An Event In Rock History. And that's a fact! Rob Halford, better known as ex-singer for Judas Priest, joined Sabbath for two gigs to support Ozzy on his last shows for the "No More Tours"-Tour because Dio refused to do so! On this boot you can hear recordings from the second concert plus recordings of the four tracks which Black Sabbath Mark I played finally at the show together and which later on lead to the plans for a great re-union with Osbourne/Butler/Iommi/Ward! Recordings are made in the crowd, so sound quality is less good then on radio shows but still ok. Released in 1993, supposed to be released by an Italian label.
