walt disney had asked the sherman brothers for their help on the project, feeling the story was too flat. the shermans wrote the song "the one and only, genuine, original family band", which was ultimately used as the title of the motion picture. after hearing the song, disney decided to add more songs to the film and turn it into a musical. in all, the sherman brothers wrote eleven songs for the film, though robert sherman reportedly did so under protest, believing the subject matter too mundane to be made into a feature-length musical film.
