I've long had this fantasy of a rock band saying to their record company "Yeah, we got this real great new song. It's about a leper who thinks that if he drinks the blood of a new born baby he'll be cured so he hangs out in the wilds until this guy leaves his wife alone with the au pair and new born child. The au pair lets him in and he cuts the kids throat and drinks the blood, gets caught in the act by the wife so he stabs her. Just as he's about to escape the guy comes back home kills him, burns the au pair to death and commits suicide."

It's just the plot of Long Lankin but what would it get to number one?
