Song written by Annette Mills - elder sister of Sir John Mills. As a dancer, Mills is credited with introducing the Charleston to England, although her dancing career was cut short by a serious car accident early in the war. Boomps-A-Daisy, the big production number on the 1939 film Band Waggon, was written by Mills, who created children`s TV programme Muffin the Mule the following year. She died in 1955 at the height of her success from a brain tumour.
