Here's another idea for The Muppet Show:
Episode 92: Original Broadway Cast of "A Chorus Line"
Opening Number: Muppets perform "I Hope I Get It" with original choreography in honor of the guest stars
Muppets participating:
Kermit, Miss Piggy, Robin, Fozzie, Gonzo, Scooter, Rowlf, Ernie, Bert, Grover, The Count,
Annie Sue, Cookie Monster, Herry Monster, Gobo, Wembley, Mokey, Red, Boober, Philo, Gunge, Emmet, Wendell, Harvey, Charlie, Traveling Matt, Bean Bunny, his brother, Lugsy, his sister, Twitch and their friends Babble, Snort, Be-bop and Bulbous, Leon, Vicki and Scooter's twin sister Skeeter (grown up and in muppet form)
Backstage: Kermit congratulates the group on a job well done and Donna McKechnie, the original Cassie, tells hime that she didn't think it could be done with Muppets. Kermit answers that she'd be surprised at what Muppets can accomplish.
Swedish Chef: Chef attempts to make tossed salad, but ingredients fly all over the place
Backstage: Donna watches the sketch and says she's surprised at what's happened and Kermit says, "Told you you'd be surprised" and tells her it's time for the casts' number
Song: Kelly Bishop (Sheila), Nancy Lane (Bebe) and Kay Cole (Maggie) sing "At The Ballet" while others dance in the background
Backstage: Kermit and the group from the opening number rehearse the closing number, "One" from the show and several mistakes are made, bumping into each other, forgetting the words and doing the wrong dance steps.
At the Dance: Rizzo and Yolanda, Two Whatnots, George and Mildred and two pigs
UK Spot: The Gills Brothers sing "Mr. Sandman"
Backstage: Kermit and the group continue to rehearse the closing number and in the process, Grover stumbles and falls causing the whole group the fall to the floor. Kermit gets frustrated and leaves thinking they'd never be ready and everything is going wrong. The guests reappear and Priscilla Lopez (Diana) explains that even when things go wrong, they still have to try again. In doing so, she sings "What I did for love" and during the song, the original cast fills in as well as Kermit and all who participated in the opening and sings along.

Closing number: Muppets from opening and guests sing "We're not gonna stop" from The Muppets at Walt Disney World and end with "One" with original choreography, even the kicks
