"Let's Go Fly A Kite" is a song from Walt Disney's film Mary Poppins, and it is composed by Richard M. Sherman and Robert B. Sherman. This song is heard at the end of the film when the story's protagonist, "George Banks" (played by David Tomlinson) realizes that his family is more important than his job. He mends his son's kite and takes his family on a kite flying outing. The song is sung by Tomlinson, Dick Van Dyke and eventually the entire chorus.

In fitting with Mr. Banks' change in character, this song was pre-recorded, and thus sung normally, by Tomlinson, rather than his previous talk-sing in the Rex Harrison style, as is seen earlier in "The Life I Lead."
