Here is a description. See if you can guess the song. More of this here.
This hymn depicts a human soul responding to the call of Christ—but the music is whiny and grim, evoking in most people’s minds a can of rancid potted meat, being slowly spread by windshield wipers across a plate of dirty auto glass. You hear Christ calling, all right—but you feel like He’s some hobo who’s tapping at your window at 4 a.m. to wake you from a sound sleep so He can ask you directions to Dunkin’ Donuts. You don’t so much want to answer Him as clock him with a slipper. Sung in a sleepwalking, zombie rhythm, its use at Communion time produces a strikingly cinematic effect, which film critics have dubbed “The Church of the Living Dead.” Here again, we have a chance to bring good out of evil: In preliminary tests, use of this song by military interrogators has proved a successful, slightly more humane replacement for water-boarding.
