Becoming very popular on French radio and television, where she had a number of hits in the 1960s and the 1970s, she was considered as part of what is known as the French yé-yé generation heavily influenced by American music, particularly R&B, Rock and roll and Beat music. She is mostly known for her version of "Mamy Blue".
