A Partially Uncensored Back to the Past

This is probably the most obscure source I've ever used, so if anyone else recognizes it, please tell me immediately. See, there was this set of cassette tapes my mother bought for me from the dollar store back in the early 1990s for me to listen to as I was falling asleep. They all had dinosaur-related songs and stories on them, one of which was called "Back to the Past". I listened to that one a lot.
No, I'm not doing anything horrible to my childhood, because I would have found this edit funny as a child, too.
