Signed by Serge Gainsbourg, the entirely disco-funk soundtrack for this 1977 film is enhanced by the immense arranger Jean-Pierre Sabar, featuring Marcel Azzola on bandoneon for 'Mi Corasong', not to mention the theme song 'Yesterday, Yes a Day' performed by Jane Birkin.
Directed by Just Jaeckin, creator of Emmanuelle, and starring Françoise Fabian in the lead role, Madame Claude is based on the fictionalized memoirs of Fernande Grudet, the notorious instigator of France's most famous luxury prostitution network during the Pompidou era.
