At 75, management probably felt John was too young for WGAN's audience.
On a personal note. Many years ago I took over John's position as copywriter at WPOR, Portland ME. After giving me a general rundown I asked John if there was anything else I needed to know. Without a word, John tapped the lower right hand drawer of his wooden desk with the toe of his shoe. I opened the drawer to find several full 'nips' bottles of whiskey. We looked at each other, smiled, and the rest is (albeit blurred) history.
John was also extremely generous in sharing paid agency work. He and I often worked together doing character-voice sports for a number of long-running ad campaigns. He's good people.
