There was a version of
Rudolph the Red-Nose Reindeer that Daren Streblow did I love.
"I've killed Dasher and Dancer
Prancer and Vixen
Comet and Cupid
And Donner and Blitzen...
But do you recall...
The easiest target of all?"
It's cruel, but true. XD
Jeff Foxworthy's Christmas songs are great ('Twas the Night Before Christmas and The Twelve Days of Christmas).
Obadiah from TVU's Ten Most Wanted wrote a practical parody of
O Holy Night. "O holy night, they're having a midnight sale..."
Grandma Got Runover by a Reindeer makes me laugh, but I don't really like the original.
FF5'S FTW! And speaking of FF5, they did a medley of Christmas songs that made me laugh. You can listen to it
here. It's called "Christmas Carol Blog".
As for traditional songs...I like
What Child is This? and
O Little Town of Bethlehem. Contemporary Christmas music...uh, Hawk Nelson has a new one I really like. Something about bells? XP I can't remember.
OK, I think I'm done! XD
