We are becoming, so we are told, a classless society. The class barriers are crumbling, or so they say, overwhelmed by the whizz kids, the pacesetters and the meritocrats. These days, a railway-man can marry a deb. How you do what you do, is more important than who your father was. That is what we're told. But what happens when a working class boy like Eric Parsloe becomes President of the Oxford Union? Or Mike D'Abo, after Harrow and Cambridge, chooses the world of pop instead of the Army. Or Diana Regler, born to a life of servants and tennis parties in Kenya, chooses instead to marry a fitter? Any examination of class in Great Britain must be personal. The general rules are changing and there are a great many exceptions. But class consciousness is something you don't have to look far to find - as Jeremy James discovered when he looked for examples of those who have crossed, or tried to cross, the class barrier: and those who know their place and are happy to be there.
