This information I received from two different people:
"Once again, I never even knew footage other than the two Movies "Amougies Music Power" and "European Music Revolution" existed!
Also, I was pleased to hear that it is still possible to arrange a private screening of those two movies, but unfortunately, this can only be done in France, where the tapes are to be found. Some info here:
here is the original link, in french: http://www.rock6070.com/forum/viewtopic.php?f=5&t=7453
The last commenter talks about how he arranged such a screening, and provides a link to the French Film archives. So who knows, if you ever go to France sometime...."
"Do you know I
recently had the chance to finally see the 2 colour movies about the
festival ? (4 hours !)
Well it was on a smal viewer at the french movies archives or CNC (and
of course I wasn't allowed to record it) but I have seen them !
The man who made for me the projection told me it will be out soon for
a movie musical festival (but I don't know where & when !)
There was a lot of free jazz but also Gong (great but too short !),
Soft Machine, Pretty Things (including a jam with Zappa), East Of
Eden, Caravan, Ame Son, The Nice, Captain Beefheart and a lot of Pink
Floyd (also including the jam with Zappa)
... But unfortunally no Blossom Toes
I hope these movies will see the light one day on dvd (with more Gong
footage & the Blossom Toes !) "
