Verne Langdon wrote and recorded a haunting song called "The Carnival of Souls" It was released on an album with a version played on calliope, one on music box, one on harpsichord, one instrumental, one sung like a movie title song and one as a pop vocal. Yet with all those versions of the song, there seems to be no place on earth to get the sheet music. Take a listen to a few versions here.
In 1974 Verne Langdon recorded a perfect record for Halloween called "The Vampyre at the Harpsichord" (TVATH) . Highly recommended for your spooky music collection.
