Ok so my opinion on the DVD is they made a mistake to have the blank/blackouted sections. They could have either only had the actual footage on the DVD or sourced more footage for the release from other shows at the garden to give an over all view on his shows there.
For example the site http://www.msg1972.com/ or youtube have a fair few videos of his shows at the garden. They could have sourced some of these and cleaned them up and released them.
The like the release I just think that they could have added more footage after all it is out there. Who knows maybe they tried to but it feel through for what ever reason.
The footage that there is great and excellent quality and i am really pleased they released it offically in this set.
