Wossy gets all Christmassy tonight and has a rake of guests joining him to get you into the festive spirit. First up, Britain's Got Talent judge David Walliams will be on chatting about his new family comedy 'The Boy in the Dress', then he'll have veteran actress Barbara Windsor of EastEnders fame - hopefully she'll answer those rumours about whether she's returning to the soap for the 30th anniversary live episode or not. Current F1 world champion and recently announced Sports Person of the Year Lewis Hamilton will be in, and Doctor Who himself Peter Capaldi will also be stopping by. There will be laughs to be had from 8 Out of 10 Cats host Jimmy Carr, and finally there will be music! What would be 2014's dream acts to perform on the show? Would it be Ed Sheeran? And perhaps Frozen's Idina Menzel singing 'Let it Go'? Well, you've got it!
