We live, my friends, in dark times. Government cuts hit hard, while those in charge seem unable to portray themselves as anything other than pocket-lining toffs or painfully old-fashioned dullards. Her Majesty’s Opposition is presided over by a well-meaning scruff who seems perpetually at risk from being ice-picked by his jealous parliamentary colleagues. Industrial strikes abound, wars of various sorts rage away in the Middle East, nationalist parties gain popularity, and to top all the fun, a sparklingly intelligent Democratic US president is on the verge of being replaced by an over-coiffured, dangerous Republican thicko. Hey, wait a minute. Haven’t we been here before? About… ooh… 36 years ago?
