Neither have I!
I didn't bother taping this because I already got it when Prime here in Canada started airing classic SNL last August. They showed edited hour-long episodes, so I wasn't very optimistic at first. I expected they would probably show the episode where Scred and Lily Tomlin sing together, (since according to TP that one usually stays in the re-runs.) but none of the rest. I was very delighted to be wrong, though! They showed eight in total, and I got all of them. They were (in the order they were aired) :
1. Peuta's darts (George Carlin - debut episode)
2. Gorch on the brink of default (Paul Simon)
3. Scred and Lily Tomlin (host) sing "I Got You Babe"
4. Ploobis and Scred get drunk (Richard Pryor) the funniest, IMO
5. Peuta and Scred's affair (Buck Henry/Elliot Gould)
6. Scred dressed up as bee talking with Gilda Radner (Dudley Moore)
7. Gorch destroyed (Anthony Perkins)
8. Mighty Favog tells them to "pack it in" (Raquel Welch)
I was a bit disappointed they didn't air the "crater head" skit. (they aired the episode, but the skit was cut) I also would liked to have seen the one where Peuta and Scred....um....spice things up!
But I can understand why they decided not to air these two skits in particular. They aired at 5pm, and at that time it would have been too easy for young kids to see them. Of all the skits, I'd say these two are probably the most risque.
It would be nice if Henson made these available to the public on DVD, because these skits are so unique -- more adult than anything the Muppets have ever done before or since. Unfortunately for that very reason, I doubt they ever will.
