How about "Rudolf, the Red-Nosed Reindeer," by Jerry Marks?
Most great pop songs seem to have been written by Jewish guys. Including a fantastic melody by a fellow born into a Jewish family, who later converted to Reformed Christianity. His name was Felix Mendelssohn, and the song is "Joy to the World."
Now that is really interesting. The words to that song explicitly celebrate the reason for the season-”Joy to the world, the Lord has come. Let earth receive its King!” I love it!
