I have a couple of gems on top of all the vinyl, cds, bootlegs, books that I have.
What you can see here are two super 8 cine films, the one on the left is I believe to be Canada 1972, and is a 50 foot length silent B&W, shot from the audience, and has the JPJ symbol draped over the keyboard, so you can narrow that down to a certain time, as he didn't do that for long.
The other is official, which I bought in about 1984 ( I think it was out before the VHS version) from new, from a shop in London. My Dad has a sound projector, and he told me at the time that this was for sale, so I bought it, it's 400 feet in length, colour sound, condensed version of the film. It cost me about £25 at the time, and I have NEVER seen another one for sale on ebay or anywhere else.
