Since Bebe and Louis Barron did not belong to the Musicians Union, their work could not be considered for an Academy Award, in either the "soundtrack" or the "sound effects" categories. MGM declined to publish a soundtrack album at the time that "Forbidden Planet" was released. However, film composer and conductor David Rose later published a 7" (18 cm) single of his original main title theme that he had recorded at the MGM Studios in Culver City during March 1956. His main title theme had been discarded when Rose, who had originally been hired to compose the musical score in 1955, was discharged from the project by Dore Schary sometime between Christmas 1955 and New Year's Day. The film's original theatrical trailer contains snippets of Rose's score, the tapes of which Rose reportedly later destroyed.
