This week Chris Serle joins the festive mood with a view of Christmas past from the largest film and videotape library in the world. A Christmas-box selection from shows like Dave Allen at Large, Some Mothers Do 'Ave 'Em, Hugh and I, The Good Life, and a sequence from The Morecambe and Wise Christmas Show which was seen by 28 million viewers on Christmas Day 1977. Guest Jeremy Unwin , Young Cathedral Chorister of the Year, joins Chris in 'Good King Wenceslas'; and John Craven recalls when he met Mother Teresa for Newsround, and what that means for Christmas. There's even a look at London on Christmas Day 1949, and veterans of the First World War tell of the time the war stopped because it was Christmas Day.
