"Mickey Mouse March" is the theme song for Mickey Mouse Club, a children's television series that originally ran from 1955 to 1959 on ABC. It has since become the official theme song of Mickey Mouse and can be heard in many Disney productions. The song was reprised with the slower "Now it's time to say goodbye" verse and different lyrics at the end of each episode that became the show's alma mater. The song remains popular as a children's music standard. The song was written by the Mickey Mouse Club host Jimmie Dodd. It was published by Hal Leonard Corporation, July 1, 1955. Dodd wrote other songs used over the course of the series. Dodd was a guitarist and musician hired by Walt Disney as a songwriter. Dodd also wrote the "theme day" songs accompanying it on the show.
