At some point in the early 1960s Jennings was supplanted in the Observer by someone altogether more bracing: Michael Frayn. It was about the time of That Was the Week That Was and Private Eye, and though as far as I know he never had anything to do with either of them, Frayn was absolutely in tune with the Zeitgeist; in fact I wouldn’t be at all surprised if I first came across the word ‘Zeitgeist’ in one of his columns, probably in the guise of a German art critic called Ludwig von Zeitgeist.
