"Ding Dong Merrily on High" is a popular Christmas carol.
During the Christmas Medley in A Muppet Family Christmas, the first verse was sung by Scooter, backed by chickens and the casts of The Muppet Show and Sesame Street. It gets the attention of the main cast of Fraggle Rock, inciting them to check out where these songs are coming from, and ultimately luring them from out of Fraggle Rock into "Outer Space".
