I admit I never listened to him.
Just not a radio listener then and cannot hear squat now.
Did read much of one of his books at least.
There were enough quotes floating around over the years that I had a decent grasp of his insight about things.
His insight wasn’t the half of the show’s entertainment value. It was great, riding along as he had “more fun than a human being should be allowed to have” for three hours a day.
