Yep. We've got a CD with songs from Muppet Family Christmas that some fan had ripped and posted online, and we listen to it in the car every year.
In this cut-down version of the special, the isolated NBC poem by Ernie and Bert is immediately preceded by a soundbyte from Kermit to Robin, and I can't tell you how many times we've each expressed the opinion that without the visuals, the Ernie lines sound more like Kermit. (A misconception strengthened by hearing Ernie talk to Rowlf and call for the curtain to open and close.)
Finally I decided to just cut the poem down by itself and see what it would look like coming out of Kermit's mouth instead. That video was the result.
Happy holidays!
