MusicXML scores for euphonium by Petula Clark

Petula Clark CBE (born 15 November 1932) is a British singer, actress, and songwriter. She started her professional career as a child performer and has had the longest career of any British entertainer, spanning more than 85 years.

Clark's professional career began during the Second World War as a child entertainer on BBC Radio. In 1954 she charted with "The Little Shoemaker", the first of her big UK hits, and within two years she began recording in French. Her international successes have included "Prends mon coeur", "Sailor" (a UK number one), "Romeo", and "Chariot". Hits in German, Italian and Spanish followed. In late 1964 Clark's success extended to the United States with a four-year run of career-defining, often upbeat singles, many written or co-written by Tony Hatch and Jackie Trent. These include her signature song "Downtown" (US number one), "I Know a Place", "My Love" (US number one), "A Sign of the Times", "I Couldn't Live Without Your Love", "Who Am I", "Colour My World", "This Is My Song" (by Charlie Chaplin; a UK number one), "Don't Sleep in the Subway", "The Other Man's Grass Is Always Greener" and "Kiss Me Goodbye". Between January 1965 and April 1968 Clark charted with nine US Top 20 hits in the US, where she was sometimes called "the First Lady of the British Invasion".

Clark has sold more than 68 million records. She has also enjoyed success in the musical film Finian's Rainbow, for which she received a Golden Globe nomination for best actress in a musical, and in the stage musicals The Sound of Music, Blood Brothers, Sunset Boulevard and Mary Poppins.
