I took a day trip to NYC yesterday and went to the Paley Center for Media and spent the day looking up pure Muppet gold in their archive collection! I viewed episodes of The Tonight Show with Jim Henson from 1974 (a performance piece with a large rubberband face with Dave Goelz who looked so young and in awe that he was there!), 2 episodes from 1975 (Dr. Teeth and Kermit) and 1976 (Swedish Chef, Kermit and Fozzie) and an episode of The Cher Show from 1975 with the Muppets (the Electric Mayhem and Sweetums were featured). The only bummer was that the Tonight Show episode that I REALLY wanted to see from 1977 (Jim with Link Hogthrob!) hadn't been digitized yet and they needed a 24 hour notice to retrieve the tape from their archives. Oh, well. Another trip for another day. Muppet fans should definitely try to go there, the staff is so friendly and helpful.
