Gypsy

A musical based on the memoirs of Gypsy Rose Lee was a project of producer David Merrick and actress Ethel Merman. Merrick had read a chapter of Lee's memoirs in Harper's Magazine and approached Lee to obtain the rights. Jerome Robbins was interested, and wanted Leland Hayward as co-producer; Merman also wanted Hayward to produce her next show. Merrick and Hayward approached Arthur Laurents to write the book. As he relates, Laurents initially was not interested until he saw that the story was one of parents living their children's lives. Composers Irving Berlin and Cole Porter turned the show down. Finally, Robbins asked Stephen Sondheim, who agreed to do it. Sondheim had worked with Robbins and Laurents on the musical West Side Story. However, Merman did not want an unknown composer, and wanted Jule Styne to write the music. Although Sondheim initially refused to write only the lyrics, he was persuaded by Oscar Hammerstein to accept the job. The creative team was in place.
