(“Addams Family Theme/Overture”)
The eccentric, morbid, fun-hearted Addams family — patriarch Gomez, his wife Morticia, their children Wednesday and Pugsley, Grandma, Uncle Fester, and servant Lurch — are celebrating their yearly ritual of summoning their ancestors from the dead. As they do so, they explain to the audience what it means to be an Addams: one must have a sense of humor, a taste for death, passion, and must stir always stir things up. The Addamses summon their ancestors by dancing on the graves. From the Addams family crypt emerge the ghosts of their ancestors, dressed from all different time periods. The dead and the living come together to dance and celebrate their unique family values (“When You’re An Addams).
