From the Television Obscurities YouTube channel, here’s a dual promotional spot for short-lived sitcom Joe and Sons (CBS, 1975-1976), starring Richard Castellano. The first part is a local promo for CBS affiliate WCAU in Philadelphia. The second part is a CBS network spot for the show.
I lived in Philly for many years, so I remember WCAU! In 1975, it was a CBS O&O, Today it’s a NBC O&O!
