as indicated in the liner notes, the track "theme from mary poppins returns" was not used in the final film; it was, however, featured in trailers for the movie. one song deleted from the film before a cast recording was made, "the anthropomorphic zoo" - a song originally intended for the "royal doulton bowl" sequence - is excluded from the soundtrack album, but a demo recording, illustrated with storyboard images, is included as a bonus feature on the home media release of the film.
