Joan Benny talks about Jack Benny and his violin.

Joan Benny: My father was a very good friend of Harry Truman, when Harry Truman was in the White House.  And my father went to visit him.  And they used to play duets, cause Truman played the piano.  And they loved to play duets together.  So my father goes to the White House, and he’s carrying his violin case, and he gets there, and the guard – security, of course, says, “Mr. Benny, I hate to ask you this but I have to.  What are you carrying in that case?  And my father to be funny said, “a machine gun.”  And the guard said, “Oh thank God, I thought it might be your violin.”
