For the first time in their careers, all the Muppets (except the ones that couldn't make it, like the Doozers, Gorgs and most of the Fraggles) have gathered together in one place to celebrate their thirtieth anniversary and honor the one who brought them together: Kermit the Frog (and by doing so, Jim Henson).

In this one-hour special taped between March 9-17, 1981, Lily Tomlin and Dudley Moore join the Muppets in a tribute to film classics. Kermit the Frog hosts the program, which begins with an all-cast rendition of "Hey a Movie!" from The Great Muppet Caper.
