that's the one : charles aznavour, another long-time favourite : http://www.youtube.com/watch?v=L7qyMBDDjvU
in my head, he had faded away a little bit, untill some months ago, when i saw him singing together with a young french singer, fabien marsaud, also known as "grand corps malade". this one has the kind of voice, that has almost the same attraction to me, as Leonard Cohen's voice : deep, strong, and warm, and on top af that, he makes songs that mean something, "words that mobilise", as some other heavenly voices would say.
this is their duet ; it's great to see this 86-year young perform with a young rising star : http://www.youtube.com/watch?v=ONmRMPXYtq4
this is a song that explains why this young man is less "mobile" than his old friend http://www.youtube.com/watch?v=KxzUCFwx52A&feature=related
i hope these links may bring this voice to some more listeners ; i absolutely adore the voice and the words
i think i know your singer, indeed more famous for an other instrument, than his voice, but i'll leave it to someone else)
