Today we have Emmet Otter's Jug-Band Christmas which stars the voices of Jerry Nelson, Melissa Rabbit, Frank Oz, Marilyn Sokol, Dave Goelz, Richard Hunt, Eren Ozker, and Jim Henson.
The program as originally aired no longer exists due to various edits made over the years. The video below is from a fan who laments these changes. For reference purposes, here's a list of the changes that have been made.
Plot: What do you do if you are poor otter with a great singing voice who wants to buy a gift for a loved one at Christmas? You enter a singing contest with hopes of winning the $50 prize!!
