Hope you get to hear the episode The Shadow Challenged. Not only is it one of the best shows, but the villain was played by Frank Readick, who had been The Shadow before Orson Welles (Bill Johnstone, who followed Welles in the role, played the Shadow in this episode). In the Welles' shows, the opening and closing signatures are by Readick, not Welles, because Readick did the Shadow laugh better, and had a creepier voice.
