The comedian hosts an extended show filled with festive fun and frolics, plus the odd song or two by the evening's house band. Chatting to Alan on the sofa are broadcasting legend Terry Wogan, comedienne Sarah Millican, This Morning presenter Phillip Schofield, actor Dan Stevens - star of Night at the Museum: Secret of the Tomb - and Celebrity Big Brother presenter Emma Willis. All the guests join in with Gino D'Acampo for some Christmas cooking, and there's live music by singer-songwriters Sam Smith and George Ezra, and pop supergroup McBusted.
