First there were the real-life eccentrics: Edith Bouvier Beale and her daughter, Edie, related to Jacqueline Bouvier Kennedy Onassis. Then there was the 1976 cult documentary Grey Gardens, about their living in a decaying mansion so filthy it was declared a health hazard. Then, last year, there was the Off-Broadway hit musical about them. Then the musical moved to Broadway, where it was an even bigger hit and where it happily resides at this very moment.
