Petula Sally Olwen Clark, CBE (born 15 November 1932) is an English singer, actress, and composer whose career has spanned seven decades.

Clark's professional career began as an entertainer on BBC Radio during World War II. During the 1950s she started recording in French and having international success in both French and English, with such songs as "The Little Shoemaker", "Baby Lover", "With All My Heart", and "Prends Mon Cœur". During the 1960s she became known globally for her popular upbeat hits, including "Downtown", "I Know a Place", "My Love", "Colour My World", "A Sign of the Times", and "Don't Sleep in the Subway". The timing and popularity of these songs caused Clark to be dubbed the First Lady of the British Invasion. She has sold more than 68 million records throughout her career.
