Composer and arranger John Leavitt is well known for bringing his concert and classical sensibilities to his arrangements. This trait rings loud and clear in this medley from “Mary Poppins” with an optional chamber orchestration. Includes: “Chim Chim Cher-ee, Let’s Go Fly a Kite, A Spoonful of Sugar” and “Supercalifragilisticexpialidocious.”
