Anything Goes: A History of American Musical Theatre Ethan Mordden. New York: Oxford University Press, 2013.To use his own phrase, Ethan Mordden really Knows Stuff (xi). He is such genial genius that even when he wears us out with detail, we never doubt the authenticity of his facts or the aptness of his perceptions. Indeed Mordden lavishes on the musical the kind of treatment it deserves-big, bold, and boisterous.His survey opens almost three centuries ago with The Beggars Opera (1728), whose staging first wedded plot to song. This new style was further shaped by comic operettas of Gilbert and Sullivan, zany musical comedies of Offenbach, highly structured minstrel shows, burlesque farce, and fairytale extravaganzaseach adding its own flavor to what Mordden calls the First Age. In the Second Age, beginning around 1900, musical plays borrowed more sophisticated song and dance from vaudeville revues, most spectacularly Ziegfeld's Follies. Meanwhile, Victor Herbert's productions gave rise to the important score. Mordden discusses Herbert's seminal The Red Mill (1906) one act at time to illustrate how play's narrative can be expressed through songs. Mordden's precise and sensuous description of music and staging makes us feel as if we're in the first row on opening night.Although these early chapters may be fascinating, they can't fully escape an antiquarian feel. Happily, Mordden's prose and gusto catch fire when he celebrates the Third Age, beginning in the 1920s. Finally we get to savor guru's pronouncements about an era with which we are fondly familiar. In the older operetta, music told the story; in the new musical comedy, like No, No, Nanette (1925), the script tells story that is enhanced by song. Quotable phrases abound in this section: sequels don't work (132); Gershwin composes a chowder of whorehouse piano and Puccini (154); Ethel Merman commands the stage with her psychotronic personality (134). Mordden gives us the insider's lowdown on everything from Showboat to Titanic, from Porgy and Bess to Wicked, from West Side Story to Nine. He is nimble tour guide, pointing out the essential and challenging the obvious. Each chapter packs the clout of book. Mordden draws on his meticulously researched volumes about the Broadway musical from the 1920s to the 1970s and about luminaries like Flo Ziegfeld, Lorenz Hart, Richard Rodgers and Oscar Hammerstein, Jerry Bock and Sheldon Harnick, and Kurt Weill and Lotte Lenya. …
