With loving detail, Mordden highlights the shift in Broadway from shows that were mere star vehicles, showcasing a big-name talent, to the bolder stories, stuffed with character and atmosphere. During this period, subject matter became more intricate, even controversial, and plots more human and complex. Mordden demonstrates how, in response, musical conventions were polished, writing became more finely crafted, and dance became truly indispensable. Along the way we meet the key players: such greats as Ethel Merman, George Abbott, Jerome Robbins, Gwen Verdon, Bob Fosse, Stephen Sondheim, Frank Loesser, Cole Porter, Leonard Bernstein, and many others. We get the backstage scoop on why Guys and Dolls is so well-made, why West Side Story is so timeless, why The King and I and Gypsy pushed the envelope, and why no one ever talks about Ankles Aweigh. All this is peppered with a dash of industry gossip -- the directorial struggles, last-minute script rewrites and cast replacements, the power of the poster listings -- that made made Broadway so nerve-wrackingly vibrant.
