Its best-known version was created by James Cobb and producer Buddy Buie for the group Classics IV when they added lyrics about a "spooky little girl". The vocalist was Dennis Yost. The song is noted for its eerie whistling sound effect depicting the spooky woman. It has become a Halloween favorite.
