Merry Christmas to all also from BerrumpapumBing and BerrumpapumBowie

This is amazing! David Bowie, it seems, just happened to be passing by Bing Crosby's house and popped in for a chat and then completely out of the blue they sang a lovely song and what's more its all captured on camera. What are the chances of that happening?! Its not Terry Wogan and Aled Jones, but its not a bad attempt.
