BACKSTORY: My father moved us from sunny San Diego to frigid Philadelphia in December 1966 for a job at WFIL radio station. At that time, the format was Top 40, and WFIL ruled the roost. The local ABC TV station, also named WFIL, was housed in the same building on City Line Avenue. I remember watching Chubby Checker being filmed there. In 1968, due to a new FCC ruling, WFIL-TV became WPVI-TV.
