Chuck,
I'm assuming you understand that the 1975 Fur clip is exactly the same as what was shown on the 1976 Unpaved episode. There is nothing different about the actual Fur song except for whatever non-related animation/film clips preceded/followed it.
Fur was re-recorded in the '90's, but that's a whole other matter.
The chanes of anyone having that exact episode are slim to none since the very first VCR's debuted in the mid-seventies. And even then, most people didn't have them until the early eighties. Maybe I'm misunderstanding what you are looking for though.
