In 1987 Chuck Schaden was writing a book on the history of WBBM radio. He taped a one hour interview with Mal talking about WBBM in the post-war years and Mal’s career there. There is a lot of real inside baseball here about Chicago radio in the 50’s and 60’s. The audio came off of a cassette not intended for air and is not great; playing time is just under 57:00.
Chuck Schaden went on to be inducted into the Radio Hall of Fame for his work in documenting the early days of radio.
My original note said the tape was done in 1988. Actually, Chuck put a date on the cassette. It was recorded Nov 16, 1987.
