"do you know anything about Phil Cook "The Radio  Chef" or Victor Fleming?  
They were the "Two Dark Knights" on Edison  1927-28 and also went by Cook & 
Fleming on the Plaza  labels.

But on two of the Plaza sides they are  listed as "Cook & Mitchell". Do you 
know anything about  this "Mitchell"? He is certainly not Victor Fleming 
and sounds completely  different. I never found out his first name either.."

  Can anyone assist on this  query?
