This song reminds me of Marie Trintignant, the daughter of Jean Luis Trintignant. The latter actor has played the character of Julien Vercel in one of my favourite movies, Vivement Dimanche!. A Ton Étoile is a song by the French "Alternative Rock" group Noir Desir. The singer is Bertrand Cantat, who has been convicted for murder (not homicide, if I got it right) of Marie in Vilnius in 2003. Quand on a pas le choix, il nous reste le coeur. If you do not have any choice, the heart remains (or however you would say that in English). Thx to Nagy Gábor who reminded me of the song.
