Who has the right to tell your story? Especially when it’s the same story told from the differing memories of two legendary show business siblings? And one sister’s version is about to become a big, Broadway musical that is also destined to become legendary? June Havoc was famously ambivalent about the show Gypsy, which her sister, the burlesque star Gypsy Rose Lee, referred to as her legacy. And in Fable, which is itself a fable about the creation of that musical fable, the sisters’ loyalty to each other is tested in a mounting battle that takes place in rehearsal rooms, dressing rooms, onstage, backstage, and all in the memory of the aging Ms. Havoc as she faces her imminent death, still battling with fiction and truth in order to keep her own legacy alive.
