Fans of the 2001 film Jeepers Creepers will remember the song below by Henry Hall, a British band leader from the 1920's to the 1950's. It was even scarier than the title track, a real bright spot in that movie.
His tunes sound like they were directed at kids... but kids he wanted to terrify. And he performed another tune, just as utterly satanic. It was about a teddy bear picnic. Really.
