A slogan is a memorable motto or phrase used in a political, commercial, religious, and other context as a repetitive expression of an idea or purpose. The word slogan is derived from slogorn which was an Anglicisation of the Scottish Gaelic sluagh-ghairm tanmay (sluagh "army", "host" + gairm "cry"). Slogans vary from the written and the visual to the chanted and the vulgar. Their simple rhetorical nature usually leaves little room for detail, and a chanted slogan may serve more as social expression of unified purpose, than as communication to an intended audience.

Marketing slogans are often called taglines in the United States or straplines in the U.K. Europeans use the terms baselines, signatures, claims or pay-offs.

Jane Mallory Birkin, OBE (born 14 December 1946) is an English actress and singer who lives in France. In recent years she has written her own album, directed a film and become an outspoken proponent of democracy in Burma.

Jane Mallory Birkin was born on 14 December 1946, in Marylebone, London. Her mother, Judy Campbell, was an English actress, best known for her work on stage. Her father, David Birkin, was a Royal Navy lieutenant-commander and World War II spy. Her brother is the screenwriter and director Andrew Birkin. She was educated at Upper Chine School, Isle of Wight.

Birkin emerged in the Swinging London scene of the 1960s, appearing briefly in the 1966 film Blowup, and as the fantasy-like model in the psychedelic Wonderwall from 1968. That same year, she auditioned in France for the lead female role in Slogan. Though she did not speak French, she won the role. She co-starred with Serge Gainsbourg, and performed with him on the film's theme song, "La chanson de slogan" — the first of many collaborations between the two. In 1969, she and Gainsbourg released the duet "Je t'aime... moi non plus" ("I love you... me neither"). Gainsbourg originally wrote the song for Brigitte Bardot. The song caused a scandal for its sexual explicitness, and was banned by radio stations in Italy, Spain, and the UK.

Serge Gainsbourg, born Lucien Ginsburg (French pronunciation: [sɛʁʒ ɡɛ̃sbuʁ]; 2 April 1928 – 2 March 1991) was a French singer, songwriter, poet, composer, artist, actor and director. Gainsbourg's extremely varied musical style and individuality make him difficult to categorize. His legacy has been firmly established, and he is often regarded as one of the world's most influential popular musicians.

He was born Lucien Ginsburg in Paris, France, the son of Russian Jewish emigrants, Joseph Ginsburg (28 December 1898, Kharkov (Ukraine) – 22 April 1971) and Olga Bessman (1894 – 16 March 1985), who fled to France after the 1917 Russian Revolution. He had a twin sister, Liliane. His childhood was profoundly affected by the occupation of France by Nazi Germany, during which he and his family, as Jews, were forced to wear the yellow star and eventually flee Paris. Before he was 30 years old, Gainsbourg was a disillusioned painter, but earned his living as a piano player in bars.

He first married Elisabeth "Lize" Levitsky on 3 November 1951, and divorced her in 1957. He married a second time on 7 January 1964, to Françoise-Antoinette "Béatrice" Pancrazzi (b. 28 July 1931), with whom he had two children: a daughter named Natacha (b. 8 August 1964) and a son, Paul (born in spring 1968, after Serge had gotten back together with Béatrice). They divorced in February 1966.
