I listened to WABC also, starting a couple three years earlier than you. In addition to Cousin Brucie who did evenings, there was Dan Ingrahm in the afternoons and Herb Oscar Anderson in the mornings (shared with the Breakfast Club from 10am to 11am).In the early 1960's WABC also simulcast on WABC-FM (95.5) until 6pm when WABC-FM switched to classical music for the rest of the evening.Not many people had FM radios in the early 1960's. The FCC had to make a rule that all new radios sold were AM/FM in order to get FM radios sold. Once that happened, FM radio opened up, with [mostly progressive] rock replacing classical.
