Who else sang this casablanca by bertie higgins?

Who else sang Casablanca by Bertie Higgins? I remember hearing it when i was a kid. It sounded somewhat like Prince but huskier. I miss hearing it. Anyone knows? I tried searching but i can't seem to find it

That song by Bertie Higgins is "Key Largo". I have never heard it by anyone else but have never really looked. Good Luck.
