In the summer, they belt the ol' horsehide. In the winter, they belt out songs. They're Jerry Burke and Jack Glennon, stars on the baseball field and the vaudeville circuit. Real-life vaudevillians Gus Van and Joe Schenck, whose piano act carried them to fame in the Ziegfeld Follies footlights and on early-radio airwaves, headline this spirited 1930 musical that combines World Series heroics with the quest for romance (The Broadway Melody's Bessie Love plays the female lead). The film's baseball-vaudeville scenario stepped up to the plate again in 1949 with Frank Sinatra, Gene Kelly and Esther Williams in Take Me Out to the Ball Game. Batter ' and curtain ' up, musicals fans!
