The concert footage was taken from six of the concerts on that tour. It is conclusive proof that the original quartet of Osbourne, Iommi, Butler, and Ward (or, in Osbourne's words, "four dickheads from Aston, near Birmingham") were every bit as exuberantly juvenile a rock & roll band in their early 50s as their late teens. Also included is a sketchy biography and interviews with the band by Henry Rollins, one of the countless contemporary musicians influenced by Sabbath. It's a nice idea, but the only real weakness of the package is that Ozzy is never granted time to wheel out any of his peerless reserve of grotesque rock & roll anecdotes. Nevertheless, the already formidable case for Osbourne's knighthood is strengthened further. --Andrew Mueller, Amazon.co.uk
