To GUEST.TJ: Your comment regarding Sam Hinton brought back some memories. He used to come up to LA occasionally to give some noon concerts at a major aerospace company where I was employed. These were arranged by his sister, who worked for the same company. Sam told me that he had at one time worked for a carnival, and had developed a number of unusual skills. Of the musical ones, he demonstrated that he could whistle a tune and hum the accompaniment simultaneously. He said that he could also whistle an ascending scale and hum a descending one simultaneously also, but he rarely attempted it any longer, since hardly anyone appreciated how difficult that was.
