Male Singer (Very Crooner-like)

I was in Morocco earlier this year and whilst there I had the opportunity to hear quite a bit of Arabic music and fell in love with it. One singer in particular who I always forgot to get more information about. His songs had somewhat of an old crooners style beat to them and his voice was equally deep and upbeat. Almost what it would be like if Sinatra had ever sung in Arabic. I later met a friend in Paris whom I had met in Morocco and he had also heard the music and regretfully hadn't gotten a name. Can anyone help me solve this riddle as we are both looking forward to hearing more of his music. Thank you!

Do you, by any chance, know if the singer is Moroccan? or he is from a different arab country?
that would make it easier to guess whom you are talking about
