She was born Dominique Cozette in Canteleu, near Rouen, on 14 May 1946. She began performing from a very age. At 15, she bought a guitar and began writing songs. With a school friend, she became a frequent visitor to the studios Salut les copains, where she saw many of the big stars of the day. It was there that she got to know Eddie Vartan, who suggested that she should join singer Frankie Jordan on a duet, Panne d’essence.
