On the last programme before Christmas, catch up with the latest news of the double LifeSaver Appeal, in aid of Ethiopia and the four Blue Peter lifeboats. There's Christmas Eve magic in the air as the studio is transformed into the Kingdom of the Snow for the stars of the famous Nutcracker ballet, and a carol around the tree with the massed choirs of ALLFARTHING PRIMARY SCHOOL, WARLINGHAM COUNTY SECONDARY SCHOOL plus the BBC SYMPHONY CHORUS and the BAND OF THE CHALK FARM branch of the Salvation Army.
