Whether he was thwarted by Rocky and Bullwinkle or leading visitors on a tour of the Haunted Mansion, Paul Frees' rich voice has been a part of pop culture for generations. But before all of that, he was a versatile voice actor on radio - one of the era's men of a thousand voices. We'll hear him starring as Jethro Dumont in "The Man Who Never Existed" from The Green Lama (originally aired on CBS on June 5, 1949). Then he's an impressionist roped into a scheme in "Fatal Fraud" from The Whistler (originally aired on CBS on May 22, 1949).
