Those original old radio show recordings

We now have probably a few thousand old radio show CD's, and more all the time. But this week I started back on the original group. My wife had found a supplier in Washington State who sold them in cassette form, and every once in a while we would get a group of them. We would listen to them in the car on trips, and at night when we went to bed. Because our supply was somewhat limited in those days, we would listen to them over and over again, until all of us (kids included) could almost recite the main lines. Those were some happy times.
