That Emmy appearance was interesting. Is it just me, or was Buster being performed by Richard Hunt in that appearance? It doesn't sound like Marty's voice for the character.
It is interesting that Jim was able to perform there while Frank didn't, since this was a few years before he became a director (his only directing credits being The Dark Crystal and the number three ball film). I would have thought Jim would have been the one unavailable for the appearance.
It's interesting how Forgetful Jones doesn't appear, yet Clementine and Buster do (I think i saw an additional cowboy with Clementine).
I feel like Aristotle should have been in this, since he was on the show at the time. Of course I also feel like Bruno should have been there, carrying Oscar on-stage as opposed to the trash can already being there (I wonder how much time it would have taken Caroll to change from Bruno to Big Bird, if there would have been time to do so before Big Bird entered the stage at the end).
I wonder if Brian Meehl was performing Barkley or Telly. I feel like he would have normally been inside Telly (Martin Robinson has said that he always performs Snuffy if Snuffy and Telly appear together, even if Telly gets more dialogue), and Telly's voice could have been pre-recorded (since most of it is singing). And yet there seems to be something different about Barkley's movements.
