Oh dear, we've got an hour to fill in the Radio 4 schedule, what shall we do ? I know, give Stephen Fry a call, he'll come up with something. Hey Stephen, we need an hour's radio, could you do that thing that you do, come up with something which sounds erudite, is slightly tongue in cheek and makes people feel we're fulfilling the Reithian vision of informing, entertaining and educating. Will do.
So what you get here is an hour of Mr Fry rambling away in a mildly diverting manner. It doesn't go anywhere, doesn't give any deep insights, just bungs enough weird and wonderful facts out to keep one interested. It is not, as the cover suggests, an exploration of the London cabbies' knowledge, although that is it starting point, nor is it in anything other than the most superficial sense, an exploration of the nature of knowledge, as it also puports to be. So starting with taxi drivers, Fry burbles along, using Fred Housego as an entry to mastermind and panel games in general. An amusing dip into BBC archives to listen to plummy voiced historical quiz shows (including Fry himself on university challenge) gives way to a exploration of changing technology on the storage and transmission of knowledge, also taking in Trivial Pursuit on the way.
It's OK. No great shakes, you'll forget most of it within a couple of days, but its not an unpleasant hour's listening.
