The closing reprise of "Rainbow Connection" featured a crowd of more than 250 Muppet characters—virtually every Muppet that had been created up to that point in time. According to Henson Archivist Karen Falk: "137 puppeteers were enlisted from the Puppeteers of America (along with the regular Muppet performers) to perform every Muppet extant. Prior to the day-long filming of the shot, Henson gave the enthusiastic participants a lesson in the art of cinematic puppetry. Amazingly, it did take just one day. " The Muppet Show Fan Club newsletter answered the question of "How did they do it?" The response was "There are 250 puppets in the last shot of the film, and they're all moving. How? 150 puppeteers in a 6' deep, 17' wide pit, that's how. They were recruited through the Los Angeles Guild of The Puppeteers of America and almost every puppeteer west of the Rockies reported for pit duty. " In September 1978, Edgar Bergen, Henson's idol who appeared in a cameo role, died shortly after completing his scenes. Henson dedicated the film to his memory.
