My guess is this was a television special of the early 70s. The LP was released in 1972 on RCA. You are probably saying, "Why would a TV special be released on a record album?" The answer is that this was before VHS, DVD or You Tube. This was common before home video. There was a Tonight Show anniversary special released on LP (I believe I have that somewhere). There were LPs made containing one episode of Saturday Night Live, the Smothers Brothers, Donny and Marie and Dean Martin shows. I can't find a date on when this show aired or what network, although I'm guessing NBC because of Pat Weaver and Hugh Downs involvement and it was released on RCA (NBC and RCA were part of the same company back then).
If this was a TV special, I would love to see it. This LP is filled with great audio clips from both TV and radio shows. The LP is produced in true stereo so you can hear different clips on different speakers. I want to listen to this with headphones some time. It does come with a booklet of photos, that are a kind of psychedelic collage.
This must not be a real rare LP. Several websites have unopened copies for about $20 (I gave $5 for mine). I wish I could find information on whether this is audio from a TV special or was produced solely for this record. It is a great relic from the 50s nostalgia craze of the 70s.
