More about this programme:\rbr\rbr\rbrIts Christmas Eve and Nan receives some unexpected visitors, in the form of Ghosts of Christmas Past, Present and Future. In this comic retelling of Dickens A Christmas Carol, Nan is shown the error of her ways, but is it too late for her to swap her Scrooge-like misery for some seasonal goodwill? Mathew Horne returns as Nans ever-patient grandson Jamie, and there are guest appearances from David Tennant, Ben Miller and Roger Lloyd-Pack.
