Mike Spradlin - and I totally want his book, It's beginning to look alot like Zombies: A book of Zombie Christmas Carols
Here's a sample (in case you didn't click the link or can't read Mr. Moore's blog for some reason):
ZOMBIE THE SNOW MAN
(Sung to the tune of Frosty, The Snowman)
Zombie the Snow Man was a jolly, happy ghoul,
With a corncob pipe and some boy’s nose and two eyes he got at school.
Zombie the Snow Man is a fairy tale, they say;
He was undead it’s so, but the children know how he came
Back to life one day.
There must have been a virus in that old silk hat they found,
For when they placed it on his head, he began to dance around.
Oh, Zombie the Snow Man was alive as he could be,
And the children say he ate brains all day as they tried to run away.
Zombie the Snow Man knew the brains were fresh that day,
So he said,"Please run, because it’s lots more fun when I eat your brain that way”.
Down through the village with a femur in his hand,
Running here and there all around the square, sayin'
"Decaptiate me if you can!"
He chased them through the streets of town and ate the traffic cop
And he barely paused a moment when, he heard the cops brain pop!"
Zombie the Snow Man had to hurry on his way,
But he waved good-by, sayin', "Please do cry and I'll eat your brains again someday!”
Thumpety thump thump, thumpety thump thump,
Look at that Frosty go;
Thumpety thump thump, thumpety thump thump,
Over the hills of snow.
