Links to Christmas songs

Choose the class's top-ten favourite Christmas carols/songs. You can do this by everyone handing in a piece of paper listing their top three choices. The songs chosen are written on the board and a tick is added for each choice. The ten with the most ticks win. You can either sing the songs 'a capella' or together with recorded versions you find on the net or maybe someone in class can accompany you on guitar or piano?
