As a Great War soldier-sage once wrote about Christmas in the War:-

It was Christmas Day in the cookhouse
The happiest day of the year
And all the men were merry
Cos their bellies were full of beer,
Then up stood Private Shorthouse
His face as bold as brass
Saying “You can keep your Christmas pudding
And you can stick it up your ….Tidings of comfort and joy,
Comfort and joy,
Glad tidings of comfort and joy
