The tune comes from Spooky, Scary Skeletons, a Halloween song by American singer-songwriter Andrew Gold, first released in 1996. It stayed a seasonal favourite for years before internet remixes and short-form video dances gave it a second life, turning its cheerful skeleton chorus into a shorthand for playful Halloween content. Every October it resurfaces in costumes, edits and party playlists, because the melody is instantly recognisable even to people who have never heard the full song.
