It's what they do in the New Years Treat - have people that aren't comedians.Seems a shortage of comedians there?
As far as I can make out it's two presenters, a politician, an athlete and a rapper. No out and out comedian there at all as far as I can see?
In the last one they had John Hannah (actor), Krishnan Guru-Murthy (journalist), Nicola Coughlan (actress), Rylan Clark-Neal (presenter and 'singer') and Shirley Ballas (ballroom dancer)
