Looking for a French song sung by a French female artist with a beautiful voice. Sounded more modern and like a sexual love song maybe. She was sort of moaning towards the end of the chorus.

What about the Je t'aime moi non plus description? It says it was sung by Dassin...I dont think that is correct, i dont remember Dassin singing that one,anyways, even if he did, the most famous (and original) version is performed by Serge Gainsbourg and Jane Birkin.

any advise about a song duet old french between a young boy and his father

Most of those "french" singers are jewish, just like Dassin, Gainsbourg or Barbara. Barbara is the best one, and also as a pianist and songwriter !

No songs from the great Dalida, and there are so many!
