Mary Poppins (musical)
Mary Poppins is a musical with music and lyrics by Richard M. Sherman and Robert B. Sherman (the Sherman Brothers) and additional music and lyrics by George Stiles and Anthony Drewe, and a script by Julian Fellowes. The musical is based on the similarly titled Mary Poppins children's books by P. L. Travers and the 1964 Disney film, and is a fusion of various elements from the two, including songs from the film.
Supercalifragilisticexpialidocious
"Supercalifragilisticexpialidocious" is a song from the 1964 Disney musical film "Mary Poppins". The song was written by the Sherman Brothers, and sung by Julie Andrews and Dick Van Dyke. It also appears in the stage show version.
Because "Mary Poppins" was a period piece set in 1910, songs that sounded similar to songs of the period were wanted. The movie version finished at #36 in AFI's 100 Years...100 Songs survey of top tunes in American cinema.
