At some period during my teenage years — late 40s, early 50s — there was a gospel quartet with a regional fan base via radio programs and small-town concerts. I remember its theme song, “Turn Your Radio On,” which ended with the call to “Get in touch with God; turn your radio on.” While confident in the Almighty’s capacity to use things for his purposes, I have not personally known anyone who experienced a divine epiphany channeled by radio.
