Well I was pretty close. I knew it was in that 60-61 winter because it was just before we moved to a new house which was early '61. My parents always listen to that station and it was where I got my first job in 1964.
The sad thing is that so much old radio history is lost forever. Only a fraction of the thousands of radio programs still exist as recordings- and none before the 1930s. And all the people who were a part of it are gone too. I got in the business just as the the radio pioneers were retiring. I really enjoyed hearing their tales about the early days when everything was new and experimental and nobody really knew what they were doing. It was like the wild-west in the early '20s- there were few rules and anybody who wanted a radio station could get a license just by asking. Many people had little 5 and 10 watt stations they just ran as a hobby. All these guys are gone now and with them so much unwritten history.
