Look, for example, at the new memoir by the veteran ghostwriter Donald Bain, who has written, under his name or others, some eighty books. In "Every Midget Has an Uncle Sam Costume," Bain entertainingly describes his experiences as an officer in charge of censoring American Armed Forces Television in Saudi Arabia, as a jazz musician, and as an airline public-relations flack in a happier and more free-wheeling era of air travel.
