Aerosmith Gentle Giant KBFH (Quad Reel to DVDA-V)

There's a torrent of this out there but it isn't on rutracker and it is out of seeds.
It is a DVD of a quad reel of 1975 shows of Aerosmith and Gentle Giant from the King Biscuit Flower Hour. Four channel surround and not available anywhere else except on this quad reel and the bootleg conversion to DVD!
If you don't think that sounds like the best thing ever, what's wrong with you?
Would really appreciate any help tracking this thing down.

Based on what I read online, this Gentle Giant show is the same as this concert. However, the DVD of the concert that is on rutracker only has stereo and is missing the quadraphonic mix.
Another one that looks good is "Stardrive - Intergalactic Trot (Quad Reel to DVDA-V)" so I'd appreciate a share of that one too!
