Kirsty, Kelvin and a lot of DNA

A strange coincidence, is it not? When it was announced in June that Channel 5 newsreader Kirsty Young was to take over as host of Desert Island Discs, her boss, Chris Shaw, remarked: "Five is still in her DNA." I couldn't help but note that in Monday's mediaguardian interview, Ms Young said: "Radio is in my DNA." Is that what's meant by a double helix? Her remark also caught the eye of her former employer, Kelvin MacKenzie. In his Sun column today he registers his amazement at her genetic make-up, claiming that when Ms Young worked for him at Talk Radio he thought she was away from the microphone rather too often, concluding: "At last I think I now know where she was all the time... she was on a desert island."
