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.
Sherman Brothers
The Sherman Brothers wrote more motion-picture musical song scores than any other songwriting team in film history. Film scores of the Sherman Brothers include "Mary Poppins", "Chitty Chitty Bang Bang", "The Jungle Book" (except “The Bare Necessities”), "Bedknobs and Broomsticks", "Charlotte's Web" and "The Aristocats". Their most well known work, however, remains the theme park song "It's a Small World (After All)". According to Time.com, this song is the most performed song of all time.
