Philip Marlowe on the Cheyenne TV show

In the episode Rendezvous at Red Rock on the Cheyenne television series, Gerald Mohr guest stars as Pat Keogh. Mohr, of course, was the star of the Philip Marlowe radio series. He rescues Cheyenne from a murder charge, but turns to be a kidnapper and thief. In the show, he (supposedly) plays the piano and sings. The singing may have been legit (it sounded like him), but he was not really playing the piano.
