Mike Warnke, led to a pot of gold by the light of Lucifer

Warnke, a former "priest" in a Satan-cult - now a born-again christian with a mission, committed a record in '79 A Christian Perspective on Halloween. Thanks to the Scarstuff-blog (go there for more info!) you can download it here (full-zip).

I always wanted to write him a letter and say, Mike, when were you able to have this coven of fifteen hundred people? About the most exciting thing we used to do was play croquet.
