Okay, this...really has no good explanation. Just a Macro collaboration of different Christmas carols. I feel I should apologize, but of course I won't.
This was so long that I had to put it in two parts, for the consideration of those on dial-up. Still, in each part there are 82-83 slides, so maybe it doesn't matter too much.
The songs and who sings what in order of appearance:
Master: "You're a Mean One, Mr. Grinch" from How the Grinch Stole Christmas
Ten: "What's This?" from The Nightmare Before Christmas
Nine: "Jack's Obsession" from The Nightmare Before Christmas
Jack and Ianto duet: "Baby, it's Cold Outside" specifically the Dusty Springfield & Rod McKuen version (1978). [Can be listened to on
this sight.
Martha: "Last Christmas I Gave You My Heart" by George Michael
Gwen and Rhys duet: "Winter Wonderland"
Rose: "Let it Snow"
Donna: "Rocking Around the Christmas Tree"
Mickey: "Jingle Bell Rock"
John: "Ganja" by Bitch and Animal [not really an x-mas song, but has the beat of "Angels We Have Heard on High". Listen to it
here.]
Tosh: "Blue Christmas"
Owen: "Grandma Got Run Over by a Reindeer"
!Warnings!: Not completely work safe in parts; that is, during John's part. Also, it's just a bit offensive to the very closed minded.
