By sheer coincidence, I just watched the TALES OF TOMORROW episode, "The Window" (1952), for the first time this evening --a pretty cool story where a strange broadcast repeatedly interrupts the episode they're trying to make-- and you can hear Don Medford (playing himself) in it, though you can't see him, as he's directing it all from the control booth.
