For six straight decades, one unstoppable force has flat-out dominated popular culture — breaking down barriers, pushing boundaries, and letting nothing and no one stand in her way. This is her story, and it’s packed with so much Cher that it takes three women to play her: The kid starting out, the glam pop star and the icon. The Cher Show is 35 songs, six decades of stardom, two rock-star husbands, a Grammy, an Oscar, an Emmy, and enough gowns to cause a sequins shortage in New York City, all in one unabashedly fabulous new musical.
