Lyric discussion by infamous branmuffin 

Cover art for Moonlight On Vermont lyrics by Captain Beefheart and the Magic Band

"Old Time Religion" is an old gospel song... Maybe, Captain Beefheart did choose to modify the meaning, I don't know. But those lyrics are from a traditional Christian song, not from Beefheart's imagination. Perhaps they're meant to be ironic?

I know Beefheart was listening to Steve Riechs 'Come out' when writing Trout Mask thats where he gets the 'come out to show dum' from.
