A Christmas carol for austere times

All together now!

O Christmas tree
O Christmas tree -
How lovely is your branch!
O Christmas tree
O Christmas tree -
It is a quite nice branch!

Your leaf is green -
There's only one -
It looks so lovely in the sun!
O Christmas tree
O Christmas tree -
How lovely is your branch!

The tinsel cost
To much (good grief!)
Instead we'll hang this lettuce leaf!
O Christmas tree
O Christmas tree -
How lovely is your branch!

And yes, by jove, pon my word, and flibbert my gibbert, it's in Badger's Dozen too!
