Art deco reigns supreme on the original sheet music cover for Jerome Kern & Otto Harbach's "She Didn't Say Yes" from The Cat and the Fiddle.

Jerome Kern had several hits over the course of the 1930s. Still an innovator, his shows continued to put existing theatrical forms to new uses. Otto Harbach provided the book and lyrics for The Cat and the Fiddle (1931 - 395), a romantic operetta in a contemporary setting. The story involved two music students who love each other but cannot abide each other's compositions. As a consequence, the score alternated the sweeping passion of "The Night Was Made for Love" with jazzier numbers like "She Didn't Say Yes."

Several months later, Kern and Oscar Hammerstein II and Kern came up with yet another modern operetta, Music in the Air (1932 - 342). An idealistic small town school teacher confronts the cynical ways of modern show business when he writes the hit song "I've Told Ev'ry Little Star." The following season, Kern collaborated with Harbach on the musical comedy Roberta (1933 - 295), which told the unlikely tale of an All-American fullback who finds love and success when he inherits his aunt's dress shop in Paris. Most critics dismissed Roberta as a bore, but fueled by the success of "Smoke Gets in Your Eyes," the show managed a profitable run. Beloved comedienne Fay Templeton made her final Broadway appearance as the aging aunt, introducing the rueful "Yesterdays."

Kern and Hammerstein spent most of the 1930s in Hollywood, working on a series of profitable but artistically uneven films. Their last Broadway collaboration was Very Warm for May (1939 - 59), a backstage love story featuring the rapturous "All the Things You Are." When the show failed, Kern and Hammerstein resumed their screen efforts out West. By the time Kern died in 1946, Hammerstein would be part of an even more innovative collaboration. More on that in our coverage of the next decade . . .

Cole Porter: Hit Maker
William Gaxton, Ethel Merman and Victor Moore on the sheet music for "All Through the Night" from Anything Goes.

Cole Porter had more hit musicals than any other songwriter of the 1930s. Heir to a fortune, his insider's perspective on high society delighted theatergoers, feeding their fantasies of a carefree life in the midst of the dreary Great Depression. Porter also composed scores for numerous musical films, but his stage works were the "state of the art" musical comedies of that decade –

– Gay Divorce (1932 - 248) featured Fred Astaire as a novelist who accidentally gets mixed up in a acrimonious divorce case. He introduced Porter's throbbing ballad "Night and Day," an assignment he would soon repeat on film. Always acclaimed for his dancing, Astaire's singing showed off Porter's songs to extraordinary advantage. Despite a limited vocal range, Astaire had a flawless instinct for delivering a lyric.

– Anything Goes (1934 - 420) was the definitive 1930s musical comedy, but it had a rocky gestation period. Although financially wiped out by the Depression, veteran producer Vinton Freedley pretended that he had money to spare. He signed up William Gaxton, Victor Moore and Ethel Merman for the cast, and convinced Porter to write the score. With that powerhouse line-up, Freedley was able to raise money for this tale of mistaken identities and unlikely romance aboard a luxury liner. The show required ongoing revisions, with former stenographer Merman taking down the changes in shorthand during rehearsals and typing them up for the rest of the team. Anything Goes restored Freedley's finances, cemented Porter's place in the front rank of Broadway composers, and became the most frequently revived musical comedy of the 1930s. The score included "I Get A Kick Out Of You," "You're The Top," "Blow Gabriel Blow" and the vibrant title tune.

– Jubilee (1935 - 169) was an affectionate send-up of British royalty that introduced Porter's memorable "Begin the Beguine."

Jimmy Durante, Ethel Merman and Bob Hope appear on the original cast Playbill of  Red, Hot and Blue. When agents complained about who would get star billing, Merman and Durante agreed to criss-cross billing – and took equal precedence in photos like this one. Hope was a relative newcomer at the time.

– Red Hot and Blue (1936 -183) involved one of the most idiotic plots in theatrical history -- a nationwide search for a woman who sat on a waffle iron when she was four. Ethel Merman introduced Porter's "Down in the Depths on the 90th Floor," sang the show-stopping "Delovely" with newcomer Bob Hope, and shared criss-cross top billing with comedian Jimmy Durante.

– Leave It To Me (1938 - 291) spoofed international diplomacy, with Victor Moore as a bumbling American ambassador trying to get recalled from Soviet Russia. Mary Martin made her Broadway debut singing the coquettish "My Heart Belongs to Daddy."

Merman and Lahr appear on the cover of the souvenir program for DuBarry Was a Lady (1939).

– DuBarry Was A Lady (1939 - 408) told the story of a men's room attendant (Bert Lahr) who pines for a sultry club singer (Ethel Merman). Drugged by mobsters, Lahr dreams that he is King Louis XV of France and that Merman is his infamous mistress, Madame DuBarry. The two stars stopped the show nightly with "Friendship" and the bawdy "But In The Morning No," helping theatergoers see out the unsettling 1930s with a laugh.

A laugh? Considering the dramatic changes the world – and the musical theatre – would undergo in the 1940s, Broadway might have done better to catch its breath.
