I can make a good guess. Keith Green?
Was it Keith Green?
Don't know if it's been removed from on line bio information, but if memory serves (maybe it doesn't) his family was once identified as Jewish in on line information.
This biography lists multiple nationalities/ethnicities but doesn't say the family is Jewish.
