In Disney's Mary Poppins, which song features the word "Supercalifragilisticexpialidocious"?

In Disney's Mary Poppins, the song featuring the word “Supercalifragilisticexpialidocious” is “Supercalifragilisticexpialidocious.”

The song is performed by Mary Poppins and Bert during a lively animated sequence. Julie Andrews and Dick Van Dyke sing the principal English-language vocals in the film, which was released in 1964.

The famously long word is presented as an expression used when someone has nothing meaningful to say but wants to sound impressive. The film’s lyrics also spell out the word and play with its pronunciation.

The song was written by the Sherman Brothers, Richard M. Sherman and Robert B. Sherman, who created many of the best-known songs for Disney productions. It is often confused with other Mary Poppins songs such as “Chim Chim Cher-ee” and “A Spoonful of Sugar,” but only this title uses the distinctive invented word.
