 The song is heard various times throughout the film and in the end credits.Two other songs, "Teenage Frankenstein" (also from "Constrictor") and "Hard Rock Summer" (which remained commercially unreleased until 1999) are also featured in the film.The song features the famous "ki-ki-ki ma-ma-ma" (admittedly in its popular misheard version, "ch-ch-ch, ha-ha-ha") sound effect, a trademark of the "Friday the 13th" series.
