As French politicians debated whether to give Aznavour a national hommage, like that given to rocker Johnny Hallyday last year, tributes poured in from around the world.
In the US, singers Barbara Streisand, Liza Minelli and Lenny Kravitz hailed the "great Charles".
In Armenia, the country of his family's origins, Prime Minister Nikol Pachinian is planning a day of national mourning.
Aznavour spoke to RFI shortly after the release of his autobiography Memories of my Life in 2005.
He recounted the difficult early years when he struggled for recognition, the nose operation that "helped me be, and feel, like somebody else" and his encounter with singer Edith Piaf, who launched him on the world stage.
