I am pretty sure that Vchimp was talking about the first radio stations he heard. He tied it into "Knock Three Times", which if new, was 1970, putting it into the Nixon administration. We tend to forget how young he is! It still seems odd that he wouldn't have listened to radio until he was a teenager or thereabouts.No, this was during the 1960 campaign. I recall the Kennedy HQ on Euclid Avenue in Cleveland had a version that played on street speakers all day long.
