Every Day Can't Be Christmas

From Muppet Wiki

Every Day Can't Be Christmas is a song about how Christmas wouldn't be as special if it was every day. It was sung twice in the 1996 Sesame Street special Elmo Saves Christmas, first by Santa Claus in an attempt to convince Elmo that every day can't be christmas, and later by Elmo after he becomes convinced that Christmas should only be one day a year.

A clip from Elmo's version of the song was included in A Sesame Street Christmas Carol.
