1. Who performed Janice in the pilot?
Fran Brill did.
2. I noticed in the "At the Dance" scenes, Bert was dancing around with a girl almost exactly like Ernie. There was also a blue monster with red lips and a large purple nose dancing around. Was he supposed to be the "Grover" at the dance?
That monster first appeared in a skit on The Ed Sullivan Show where he was called Thudge. That same skit featured the first appearance of the Grover puppet, who was called Gleet in that skit. Actually, most of the monsters in that skit looked like Grover.
3. Did Jerry Nelson play Statler?
Yes.
4. Did anyone notice the Muppeteers in the background of the bird skit?
I noticed a little bit, but not much.
5. Who performered Brewsters?
Dave Goelz.
6. Was it me, or did it sound like Richard Hunt played Crazy Harry?
Richard Hunt did perform Crazy Harry in the pilot. If you watch the ending, you can see Richard performing him. I don't know why Richard Hunt performed Crazy Harry. John Lovelady had previously performed Crazy Harry in The Muppet Valentine Show, and he would regularly perform Crazy Harry during the first season of The Muppet Show, and John Lovelady did perform in this special.
7. Who else thought it was cool during the closing credits when they zoomed out and showed them performing the muppets?
I thought it was cool. If ABC picked up the show, and/ or if the show was broadcast in the format that this special had, I wonder if every epsiode would have ended like that.
