The lyrics of White Christmas struck a chord with the soldiers fighting in the Second World War and their families waiting for them back home.
Here is an extract from the film which was released in 1954.
But we could have sung this one by The Corrs...
On December 10th, 2000 the Corrs played for the President of the USA and all those present at the annual "Christmas in Washington" concert. They sang So this is Christmas, (the war is over).
Which war were they referring to ? Who was the American President at the time ? When had he been elected ? How long was he elected ?
