Howard Dietz and Arthur Schwartz, the creators (lyricist and composer respectively) of the durable standards “Dancing in the Dark,” “That’s Entertainment,” “You and the Night and the Music,” and “I Guess I’ll Have To Change My Plan,” collaborated on 11 Broadway shows, most of them revues and most of them successful, over the course of 34 years. Theirs was not an exclusive partnership; Dietz also set lyrics to the tunes, sometimes entire musical scores, of Jerome Kern, Kurt Weill, Vernon Duke, Jimmy McHugh, Ralph Rainger, and Sammy Fain, while Schwartz occasionally wrote music for wordsmiths Ira Gershwin, Leo Robin, Frank Loesser, Dorothy Fields, Johnny Mercer, “Yip” Harburg, and Al Stillman.
