Much of Danny Kaye’s success onstage came from his one-of-a-kind performances. One aspect of his performance style was his scat-like singing that he called “double-speak.” Kaye would rattle off gibberish at speeds few people could reach, while staying in perfect key and rhythm with the music being played. It was a skill that he learned early in his career entertaining in the Catskills and perfected as his repertoire grew. Sylvia Fine tailored many songs to this unique facet and helped refine the performances so that they could be included in his film, television, and radio appearances.
