The theme for the TV series The Addams Family was written and arranged by longtime Hollywood composer Vic Mizzy. The song's arrangement was dominated by a harpsichord, and featured finger-snaps as percussive accompaniment. Actor Ted Cassidy, reprising his "Lurch" voice, punctuated the lyrics with words like "neat," "sweet," and "petite." Mizzy's theme was popular enough to enjoy a single release, though it failed to make the national charts.
For many years, the intro to the song has been a staple at sporting events across the Canada and the United States. It is used in basketball games with the fans yelling "DE-FENSE" instead of snapping their fingers; in hockey games the finger snaps are traditionally substituted by the opposing teams name followed by words on how poor their team is.
A music video was produced to promote the single. It featured Hammer and several of his dancers performing in their unique style around the Addams mansion, as well as most of the cast of the film. The video opens with Hammer pleading with Wednesday (Christina Ricci) and Pugsley (Jimmy Workman) to refrain from chopping his head off with a guillotine. It concludes with several scenes taking place in the Addams' backyard cemetery, including Thing crawling up and down a Hammer dancer and Gomez (Raúl Juliá) dueling in a sword-fight with Hammer over Morticia (Anjelica Huston).
The music video was played prior to the beginning of the film in its theatrical release during the first few weeks of release.
