We're celebrating Orson Welles' birthday with two of the legendary actor and director's old time radio performances. First, Welles leads us on a tour of The Black Museum, Scotland Yard's archive of murder. He narrates the tale of a faded tartan scarf wielded in the hands of a dangerous man. Then he recreates his big screen role from The Third Man in The Lives of Harry Lime. We'll hear Harry in the syndicated mystery "Mexican Hat Trick."
