Who wrote the music for Disney's Mary Poppins?
Sherman Brothers
The Sherman Brothers
The Sherman Brothers wrote more motion-picture musical song scores than any other songwriting team in film history.[2]  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.[3][4]
