The X-mas Files. Result of a secret government experiment gone horribly wrong. A medley of Christmas carols have been freakishly merged with a number of well-known classical melodies.
Joy to the World. The old Handel piece. You know.
Veni, veni, Emmanuel. The one that has Latin words that no one can ever remember.
Let All Mortal Flesh Keep Silence. Cool French hymn melody.
Silent Night. Franz Gruber's organ broke, and the rest is history.
Good King Wenceslas. I don't know who this guy was, but he apparently knew how to party.
Jingle Bells/Jolly old St. Nicholas. Two great melodies that sound great together.
In Dulci Jubilo. Sounds suspiciously like "Good Christian Men Rejoice".
God Rest Ye Merry, Gentlemen. The carol where the comma is always forgotten.
Oh Come, All Ye Faithful. A reggae version of the well-known Christmas jam.
We Wish You a Merry Christmas. Carol with rhythmic crescendo.
Will there be more? Does a bird fly? Well, I guess it depends on the bird.
