Alan Carr returns with another end-of-year show, inviting celebrity guests including David Guetta, Danny Dyer, Mel B, Greg Davies, Katherine Ryan, Kelly Brook and Nish Kumar to join him at Channel 4 HQ to welcome 2016 in a suitably raucous fashion, with Ellie Goulding and the Vamps on hand to provide the music. As was the case with last year's festivities, viewers can expect the flamboyant host's guests to take an active role in the evening's frivolities, joining him for entertaining games and specially produced sketches, and the studio audience will also be required to pull their weight in the entertainment stakes, as Alan heads into the stalls to hear their extraordinary stories
