I’m not talking about the ~80 min version with the interviews, but supposedly in the late 60’s / early 70’s, a full version of the concert only, no interviews, no special effects was shown at select theaters as a midnight showing. I think I recall seeing an ad for it in our local newspaper back then. Or am I completely imagining everything?
There’s at least a dozen different releases of the “film” (which was shot on videotape) exist, and I’ve seen it on videotape, Japanese LD (both ~80 min and song only ~50 min versions), DVD (both long and short versions) and Blu-Ray. Not only are some of the songs not complete, but there are minute, sometimes split-second differences between the transitions of the songs and interviews.
