When a biographer digs deep enough to find that a theme song from a TV show in the 1970s actually came from a 1960s musical that closed before braving Broadway, you know he's done his research. Joshua Rosenblum, a respected musical director of many Broadway musicals, took a break from the podium to write this astonishing study of Richard Maltby, Jr. and David Shire's works. In unstinting detail, he has chronicled their great successes and bad-luck failures, all the while reminding us how great a songwriting team can be without becoming household names. And speaking of households, this book belongs in every one where a musical theater fan lives.
