This is Serge Gainsbourg - French singer songwriter with singer Jane Birkin and the cover of his 1971 album: Histoire de Melody Nelson.

I don’t understand French, but it’s no big deal…this guy’s voice is so cool and so is the music.  Creepy.  Dangerous.  Must hear.

Their famous duet Je T’aime, which features some erotic breathing towards the end, is not on this album.
