A gifted mimic and dynamic actor, Jack Moyles was a key component of several classic radio shows. Whether he was in supporting roles or in the lead, Moyles brought an always engaging, entertaining presence to the microphone. In honor of his birthday, we'll salute Mr. Moyles on this week's episode of "Down These Mean Streets." First, we'll hear him as American ex-pat, club owner, and amateur sleuth Rocky Jordan in "The Nile Runs High" (originally aired on CBS on September 18, 1949). Then, Moyles is foreign correspondent O'Hara in "The Judas Face" (originally aired on CBS on July 22, 1951).
