Appearing on The David Susskind Show, this is an in depth interview with Mary Tyler Moore on the cusp of stardom. Hulu.Com currently has nine episodes of the Susskind show, including Harry Truman, Mel Brooks, Jerry Lewis, and more.
I barely remember the show even though it was on for many years. It turns out, I didn't know what I was missing as they are very interesting interviews. Watch this one and see how you like it.
