Golden globe winning best actress and Academy Award nominee Marion Cotillard lip synchs to Edith Piaf's magnificent declaration of independence from the past, Je Ne Regrette Rien by Charles Dumont and Michel Vaucaire,
1961. This is the finale for the Piaf biopic La Vie en
Rose, known in France as La Mome.
Thanks to philipechek of YouTube and of Paris, and to the Word Reference Forum for their discussion of "tremolo"a musical term for a violin's stacatto quavering which could mean insincerity when detected in a voice.
