Knees Up Mother Brown

"Knees Up Mother Brown" is a song, published in 1938, by which time it had already been known for some years.

The song dates back to at least 1918 and appears to have been sung widely in London on 11 November of that year, Armistice Night, at the end of the First World War. The 1938 version was attributed to Bert Lee, Harris Weston and I Taylor.

The song became popular in English public houses and was particularly associated with Cockney culture. During the Second World War it was performed frequently by Elsie and Doris Waters. It was also later performed on television by Noel Harrison and Petula Clark singing as a duo.

The expression "knees up" came to mean a party or a dance.

The most familiar version of the song is:

A final, partly self-parodying refrain is often added at the end of the song, particularly after a merry session at pub or party

The song can be heard sung on match days at the Boleyn Ground by fans of West Ham United Football Club; and has also been adopted by fans of other football clubs for various chants, most recognisably with the words "Who Ate All the Pies?". More recently it has been used by Brentford supporters, celebrating that their fortunes are currently better than local rivals, Fulham who were relegated to the Championship last season while Brentford were promoted to the same division, giving the version "Bees up, Fulham Down". Fozzie Bear performed this song in an 1980 episode of The Muppet Show with his mother, Emily, portraying "Mother Brown."

It was also the inspiration for the song "Step in Time" written by the Sherman Brothers for the Walt Disney film Mary Poppins. According to Richard Sherman, the dance was taught to Walt Disney, Tony Walton, and others by the Disney Studio's head of special effects Peter Ellenshaw and the Sherman Brothers witnessed them doing the dance and got the idea for "Step in Time".
