"Jolly Holiday" is a song from the film Mary Poppins. It was written by Richard M. Sherman and Robert B. Sherman. It is sung by Bert (Dick Van Dyke) and Mary Poppins (Julie Andrews) in the pastel fantasy sequence before reaching the carousel. The Oscar winning music arranger Irwin Kostal provided the much lauded orchestration. The song also appears in the musical, but it was changed to fit the story of Neleus from Mary Poppins Opens the Door.[citation needed] The Disney on Ice version was sung as "A Jolly Holiday in London".
