In September 1962 Piaf returned to L'Olympia to give her final series of concerts at the legendary Paris venue. On 25 September the singer was a special guest star at the international premiere of the film "The Longest Day". Appearing on a stage erected on the top floor of the Eiffel Tower, Piaf gave the performance of a lifetime, singing her greatest hits to a massive audience which included royalty, heads of state and a crowd of international celebrities.
A few days after this triumphant concert, Piaf went on to marry Theo Sarapo at a private orthodox ceremony on 9 October 1962. After an extended honeymoon, the couple would return to the music scene, performing their famous duo "A quoi ça sert l'amour ?" at the Bobino in February 1963.
