Her father died when she was just two and, when she first entered show business, she adopted the surname "Davey" from her mother's second husband (the "r" was added years later).
In the nearly four-minute number, which she sang in English, French and Spanish, Darvey wore a total of four costumes, including as a belly dancer.
She was also known for the "Continental Cabaret" sketch which she performed with Hill and regular sidekick Jackie Wright, and which featured a gag involving the word "supercalifragilisticexpialidocious".
In the immediate years after her last Hill show appearance, Darvey travelled the world with her cabaret act, with her then-husband, Terry Gittings (former drummer for Georgie Fame).
For a time in the early 1980s, she was based in Miami Beach, Florida, where by then The Benny Hill Show had become famous in the United States through syndication.
