Are you talking about the 'LZ DVD' that has a desert on the front cover, it's great. They missed out at least one tune form the Sydney concert I have on video tape played after the other & it shows the band walking of stage & into a car at the very end. I'm sure they have other material. I've recently seen sections of concerts that were officially recorded '75 & 77. Their SRemainsTSame soundtrack was pretty ordinary & they admitted that at the time. They've done much better concerts 'How the West was Won' is a very good example recorded the previous year ('72) from one concert in the US. The concert at Knebworth in '79 were supposed to be a proper concert video but the band weren't happy with their overall performance so it got dumped.
