Yves Montand died on 9 November 1991, twenty years ago. The life of the artist is made up of many intertwined lives: the rise of Ivo Livi, a small Italian immigrant who became an international star, the extraordinary career in the music hall, the dozens of roles on the big screen, the meeting with women who are themselves myths: Edith Piaf, Simone Signoret or Marilyn Monroe, the commitment, finally, in the political fights of the 20th century. To revisit Montand's life is to make several journeys: from the hills of his native Tuscany to the vaults of the Metropolitan Opera in New York, from the Alcazar in Marseille to the Hollywood studios, from the cabarets of the Occupation to the Olympia, from the Red Square to the White House.
