One day while I was composing, the telephone rang. A lady's voice said, "Is this John Cage, the percussion composer?" I said, "Yes." She said, "This is the J. Walter Thompson Company." I didn't know what that was, but she explained that their business was advertising. She said, "Hold on. One of our directors wants to speak to you." During a pause my mind went back to my composition. Then suddenly a man's voice said, "Mr. Cage, are you willing to prostitute your art?" I said, "Yes." He said, "Well, bring us some samples Friday at two." I did. After hearing a few recordings, one of the directors said to me, "Wait a minute." Then seven directors formed what looked like a football huddle. From this one of them finally emerged, came over to me, and said, "You're too good for us. We're going to save you for Robinson Crusoe."
