Will the Circle Be Unbroken

After Rizzo and the rats have been a nuisance throughout the Muppet Theatre during The Muppet Show episode 503, Piggy and Beauregard convince them that they get to eat only after they entertain and spread happiness. In their plea with Kermit to join the Muppet family, Joan Baez successfully helps in bringing everyone together by leading the cast in the finale performance of "Will the Circle Be Unbroken."
