Alan's Christmas special is full of festive frolics plus the odd song or two by Alan's Christmas house band McFly, who perform a special medley of their greatest hits. Chart toppers JLS also join Alan on the sofa along with ex-Dragon's Den star Hilary Devey, who just happens to chat about her two new programmes for Channel 4, and David Walliams who drops by to talk about Christmas - but more specifically his new BBC family comedy Mr Stink, based on his children's book of the same name, which aired on December 23rd, rendering this plug kind of futile. Hopefully the guests won't get as drunk as they did last year. I'm sure Ruth Jones is still traumatised after getting doused in mulled wine.
