Frank Oz and Richard Hunt alternate the roles of Miss Piggy and Mildred. Oz played Mildred in the At the Dance segment and Miss Piggy in the Talk Spot, while Hunt played Miss Piggy in the At the Dance segment and Mildred in the Panel Discussion. Additionally, Oz plays Piggy in a Veterinarian's Hospital sketch for the first time.
The "I Feel Pretty" sketch, featuring the song originally from West Side Story, was previously performed by the Muppets as an instrumental on a April 30, 1967 appearance on the Ed Sullivan Show, and then a version much closer to the one performed here was included in the TV special Julie on Sesame Street (1973)
The "I Feel Pretty" and "Gonzo the Artist" sketches were included in "The Muppet Show Book", published by Harry N. Abrams, Inc in 1978, in which the sequences were entirely illustrated by Tudor Banus.
"Inchworm," sung by Charles Aznavour is again performed in 3.16 by Danny Kaye.
