I knew Jimmy Scribner well, dated his daughter Gayle for some time in the early 50s. Both good people, especially Gayle (!)At that time Scribner was producing his radio program in the basement of his house.I assume he mailed the work to someone, but I didn't think much about it at the time.He would allow us to sit and watch him work, but we had to be quiet.As I recall, he used no notes nor script, so apparently he did adlib his stuff.
