This has been a great set of videos to talk about and they bore further research. They come from a tape that was released called “A Dream Called Walt Disney World” and it was released in 1981. You can still actually get old copies of it on VHS at Amazon. I just ordered my copy, so I can be sure.
This is the type of TV I would watch in the 70s/80s that made me want to LIVE inside the Magic Kingdom. No celebs, no clever tricks, just awesome. The special is long so it had to be cut into 3 parts.
