Francoise Hardy, Ma jeunesse fout l'camp. The song comes from the TV show, La Femme Nikita. Wikipedia has an article on the show.
Hardy is photographable and much photographed, but rarely (never?) smiling.
She's only a couple of years younger than me.
Here is a Youtube video of one of her first performances, from a French TV show of the early 60s, Conservatoire de la Chanson.
