Nicholas Parsons has been an actor – he is most adamant that he is first and foremost an actor – for almost 70 years, so it’s not surprising, given the erratic nature of his profession, that he has been obliged to assume a number of alternative guises over the years from leading man to comedy sidekick to quiz master. Yet despite this, he is no chameleon. He has somehow managed to pull off the trick of being supremely adaptable whilst remaining resolutely true to himself – you’ll never catch Parsons dropping his aitches or wearing age-inappropriate clothing. Always dapper, slightly prim and a little aloof, he is the consummate professional and, at the age of 87, more in demand than ever.
