I'd like to see any of the Buddy and Jim segments that are not on YouTube.
And I know that either episode 2 or 3 has a claymation segment involving the letter E, which I'd like to see.
I'll have to check Muppet Wiki to see what else appears in those episodes.
I'd also like to see Bob sing "Feeling Groovy". And the full English video for "Spinning Wheel". And I'd like to see the segment where Ernie and Bert share jellybeans again (has anybody had that clip? I don't think Muppet Wiki even had a picture from that segment, though pictures do appear in The Sesame Street Book of Puzzles).
I wonder if it would be a good idea to look at the Muppet Wiki guides and make a list of everything in the first 14 episodes that are on YouTube.
This is a great time for fans of classic clips. A handful of unknown episodes from seasons 10-12 have recently popped up on YouTube, in the past year we've gotten a couple of "holy grail" clips (Crack Master and Lucy in the Shy with Diamonds), and it seems like Muppet Wiki has recently added guides to quite a few episodes from the 1980s and 1990s (though I assume fans had those episodes for years and just hadn't gotten around to making the guides).
One thing that I wonder (and this might be the wrong place for this): Is the Sesame Street performance of "Spoonful of Sugar" on YouTube in English? Muppet Wiki recently added a photo and a list of performers in the segment, including the voices of Bob McGrath, Loretta Long, and Joe Raposo, but when I search for the segment it doesn't come up. If the segment has only surfaced in another language, then we wouldn't know who the performers are.
