"They're creepy and they're kooky. Mysterious and spooky. They're all together ooky. The Addams family!" The Addams Family is a new musical comedy with music and lyrics by Andrew Lippa and the book by Marshall Brickman and Rick Elice. The show is based upon The Addams Family characters created by Charles Addams in his single-panel gag cartoons, which depict a ghoulish American family with an affinity for all things macabre.
