Radio actor John Gibson of Casey, Crime Photographer and Terry and the Pirates (seen here, far left, with Dick Bertel and Ed Corcoran) was a guest of the pair for their WTIC Golden Age of Radio Program in September of 1970 (full episode here https://www.goldenage-wtic.org/gaor-06.html).

During the course of their interview he told a story of when he sensed, during a moment in the late 1940s, that television would displace radio. This early realization helped John get a head start on breaking into television after World War II.
