Most notable is the exclusion of Steve Whitmire from the credits. He is featured in a stock photo of the performers, but Rizzo and his other characters were absent from the show. Instead, Chester Rat and Yolanda Rat were featured -- Chester's vocals were performed by Dave Goelz, and Yolanda's by Karen Prell. The Rats, Camilla, and Robin were all hand puppets, and not full-body costumes. The "Spring Factory" number also included Mr. Summerfall Winter and the Robbers; no vocal talent is listed in the credits for these characters.
