Should I mention the chorus to The Barley Mow before someone else does? Sod it, I will anyway. How this would be in SI I hate to think.
Here's good luck to the:-
barrel
half barrel
firkin
half firkin
keg
half keg
gallon
half gallon
quart pot
pint pot
half a pint
gill pot
half a gill
quarter gill
nipperkin

That's what I used to sing.
