 The librettists, Howard Lindsay (I) (qv) and Russel Crouse (qv),  originally intended to use songs that the real von Trapp family had  sung. However, Mary Martin (I) (qv), who was to be in the play,  asked Richard Rodgers (I) (qv) and Oscar Hammerstein II (qv) to  write a song for her character. Due to concerns that their original  song would not mix well with the folk music, Rodgers and Hammerstein  suggested writing a whole new score, the music we know today.
