Live at Last - Black Sabbath

An unofficial album - this was released without the band's knowledge and permission by an old manager, I believe. At the time it was a big deal, because Sabbath had never released a live album. I was never particularly fond of this album, mostly from a sonic fidelity standpoint. It was later legally released in 2002, as Disc 1 of the Past Lives package (scroll down a bit for that).
