I agree with Not Now John, the film was poorly edited. The "boys", as they always do, probably wanted to make sure the music was at its best. It was also the last time they performed "A Saucerful.., Set The Controls..., (Seamus) Mme Knobs. You can't really hold it against the Floyd because in the end they performed all the songs, film or not!!!
