"Sister Suffragette" is the fictional pro-suffrage protest song pastiche sung by Mrs. Winifred Banks in the 1964 Walt Disney film Mary Poppins. The melody of the song was originally used for a scrapped piece called "Practically Perfect". It was written and composed by Richard M. Sherman and Robert B. Sherman, and was performed by Glynis Johns.
The lyrics mention Emmeline Pankhurst, who with her daughters founded the Women's Social and Political Union in Manchester. Some of the words were, "Our daughters' daughters will adore us and they'll sing in grateful chorus, well done Sister Suffragette!".
Despite the revolutionary fervor in the song, Mrs. Banks casts off her banner of suffrage at the end of the movie (at least once) to join the family in a kite-flying outing. However, this can be interpreted as not as a "casting off" but an incorporation of her family (especially her husband) into her interests.
