The original special was hosted by Kermit the Frog; however, later releases edited out the frog's narration due to legal issues. While The Jim Henson Company retained ownership of Emmet Otter's Jug-Band Christmas, the company sold the rights to the Muppets (including Kermit) to the Walt Disney Company in 2004.
This was one of my favorite Christmas specials as a child. HBO used to play it every Christmas season in the early 1980's. I still adore it as an adult and now have it on DVD.
