I didn't pick up on this biopic about Edith Piaf but what do you expect? I live in Somerset... Non Je Ne Regrette Rien has an interesting history which I doubt is depicted in the film - according to the wiki 'Piaf dedicated her recording of the song to the French Foreign Legion.[1] At the time of the recording, France was engaged in a military conflict, the Algerian War (1956–1962), and the 1er R E P (Premier Regiment Etranger de Parachutistes, First Regiment Foreign Paratroopers) — who had backed a temporary putsch by the French military against the civilian leadership of Algeria—adopted the song when their resistance was broken in April 1961. The leadership of the Regiment was arrested and tried but the Non-Coms, Corporals and Legionnaires were reaffected to other Foreign Legion formation. They left the barracks in formation singing the song that has now become part of the French Foreign Legion heritage and is sung when they are on parade.'
