Emmet Otter's Jug-Band Christmas includes bloopers, a making-of documentary, and a lost song. "Unfortunately, due to Disney's ownership of Kermit the Frog, HIT will be releasing the special with the Kermit scenes at the beginning and end of the special edited out."
Even without the Great Green One, it's still a wonderful story with fantastic music.
Note to Self: I need to make a Muppet Stuff icon. Until then, Doozers will have to do.
