Tony Iommi and Geezer Butler do most of the reminiscing whereas OZZY only gets a guest appearance. And there’s no inclusion of Bill Ward at all. But the music is spot on. NIB and War Pigs live from 1970 and Children Of The Grave from '74 with Geezer Butler wearing the biggest pair of flares I've ever seen.
Snowblind and Symptom Of The Universe are shot live from the Hammy O in '78, plus a weird concept video of Sabbath Bloody Sabbath from '74 – it's great stuff.
