Just finished watching this, loud with the DTS track, and I could almost swear I could smell the pot smoke from the audience.  The concert footage is a great time capsule, and it's well worth the reasonable asking price.  It's a true representation of the classic line-up Moodies live, and although (as others have mentioned) they could be a little rough there's wonderful energy here, a true "live" performance by a band that looks a little intimidated at the magnitude of the event they're performing at.  As such there's a nervous enthusiasm that's very fun to watch. (Kind of amusing to see that they're apparently using the Who's and Jethro Tull's speaker stacks, at least that's what stenciled on them).  I wish the performance material was completely untouched, especially the "Ride my See-Saw" encore.  Instead it's been made into a montage of various clips of the song played by the band through the years.  It breaks the "time and place" ambiance, but as mentioned in other reviews perhaps the Isle of Wight footage wasn't complete.  Small quibble, and the opening new interviews, especially with Mike Pinder at the mellotron are very worthwhile.
