Not only are the three winners of the Doctor Who competition announced, the team open their doors to the Salvation Army, Northop Junior Brass Band and the Liverpool Signing Choir for a winter-warming performance. There's also a treat from West End musical comedy, Dickens Abridged who will be giving their take on a Dickens classic. Find out how to make 'stained glass window biscuits' to treat friends and family and how to do your bit over the festive period by donating to local food banks for the less fortunate.
