Another very good cd, even if it is an old one, is "Mireille Mathieu sings Ennio Morricone".
Mireille Mathieu is a very well none french singer. My french friends can like her or not. Personnally I don't like her very much but she has a great voice and the cd is fantastic, specially one of the songs which doesn't belong to any movie and wich Morricone wrote specially for Mathieu. It's called "La Pluie et le Soleil" (The rain and the Sun).
