When rehearsals began in September 1958, Hammerstein was absent, still recuperating from his surgery. Rodgers was present, but kept falling asleep. Hammerstein was told by his son James that Kelly was ineffective as a director, and began attending rehearsals. A number of changes were made to the songs. "My Best Love", a song for Master Wang, was at first thought better suited to his sister-in-law, but when Juanita Hall could not make it work, the song was cut entirely. Rodgers and Hammerstein transformed a song entitled "She Is Beautiful" into "You Are Beautiful". The team decided to include a song for Sammy Fong to explain to Mei Li that they should not wed. In the span of a few hours, they wrote the lyrics and music to "Don't Marry Me". Once the songs were finalized, Robert Russell Bennett, who had orchestrated several of the creators' most successful previous shows, did the same for the score of "Flower Drum Song".
