Dietz continues his excellent series on Broadway musicals with a step back into the Golden Age of musicals. He covers every Broadway show from the 1940s (273 shows altogether), from John Henry (January 1940) through Jule Styne's smash Gentlemen Prefer Blondes (December 1949). As in earlier volumes treating the 1960s and 1950s and complementing the content of Thomas Hischak's Broadway Plays and Musicals, Dietz discusses the ‘book musicals’ (serious drama set to music and song) with new music as well as the revivals, revues, new operas, imports, and other works appearing in New York venues, plus pre-Broadway closings. Each chronologically arranged entry includes opening and closing dates, number of performances, crew, cast (with character names), setting, musical numbers (and performers), two-page plot summaries and critical reception, awards, book availability, and detailed recording history. Names of performers who were billed above the title are italicized for emphasis. Entries are well-written and informative, with ample quotes from the original New York theater critics. Appendixes A–H (including a chronology, discography, and filmography), a bibliography, and a detailed index complete the volume. Any lover of Broadway shows and library collections with strengths in musical theater will want to purchase this volume. Summing Up: Recommended. All students and scholars; general readers; professionals/practitioners.
