Édith Piaf made a remarkable comeback on stage at the Olympia on December 29, 1960, with the song ‘Non, je ne regrette rien’, composed by Charles Dumont. Initially thought to be at the end of her career, Piaf’s performance revitalized her and the venue. The song not only transformed Dumont’s life but also marked a significant moment in Piaf’s legacy, solidifying her status as a music icon. The piece reflects on the history of the song and its impact, including its adoption as an anthem by the French Foreign Legion.
