One of my top 5 cinematic experiences was seeing this screened on 16mm by Johnny Legend himself, from his personal collection, back in the late 90s. He also showed a bunchof nudist colony movie trailers and the only existing 6mm print of My Breakfast With Blassie (which was never officially released on film in any format, he had the print made for himself from the original negatives).
Most versions, including this one I'm pretty certain, are cut by 6 or 7 minutes but mostly just stuff that was taken out for being boring.
