Joe says he heard about this creepy LP on Howard Stern. There's one "song" available as an MP3, "Diary of an Unborn Child".
As far as bizarre Christian LPs, I gotta say, this is this most extreme thing I've ever heard. It's some full grown man with a munchkin voice, singing terrifying songs about drug use, abortion and being a fat kid and each fill me with a profound sense of dread, horror, and disgust.

(thanks, Joe!)
Update: I nosed around this site a little more and learned that it is chock full of nightmare-inducing religious LP covers. Highly recommended.

Reader comment: Clara says: "the post about the lil markie record reminded me of little marcy. little marcy was an incredibly weird evangelical christian ventriloquist. there's a page of MP3s here.
the creepiest song is "devil, devil, go away" and the most unintentionally hilarious is "i love little pussy."
