A variant:

Bless them all, bless them all,
The long and the short and the tall;
Bless de Valera and Sean McEntee
For giving us the black bread and the half-ounce of tea.
but we're saying goodbye to them all,
As back to the barracks we crawl,
If we don't get cocoa we're going to go loco,
So cheer up, me lads, bless 'em all.
