 Although this film version of "Show Boat" was quite faithful to the  show, and although it features many of the songs from the stage  version, poster advertising for the film prominently mentioned the  three additional songs written by Kern and Hammerstein especially  for the film, even to the point of downplaying the fact that nine  songs from the stage score were sung in the film, several of those  were reprised twice or more, and three other songs from the stage  version were used as background music.
