The song "Easter Parade" that the movie was based upon was first sung in
Irving Berlin's 1933 Broadway revue "As Thousands Cheer" by
Marilyn Miller and
Clifton Webb and was inspired by the annual event in New York City where people stroll down Fifth Avenue displaying their new hats (some very outrageous) and their Easter finery. The song also appeared in the Irving Berlin movie
Holiday Inn (1942).
