Ah - metrics.

Now here's good luck to the barrel
Good luck to the Barley Mow
Jolly good luck to the barrel
Good luck to the Barley Mow
Oh the - barrel, the half-barrel, gallon,
the half-gallon, quart pot, pint pot, half-a-pint,
gill pot, half-a-gill, quarter-gill,
nipperkin, and a round bowl
Here's good luck, good luck,
Good luck, to the Barley Mow

Etc.

Final chorus:

Here's good luck to the company,
Good luck to the Barley Mow;
Jolly good luck to the company,
Good luck to the Barley Mow;
Oh, the - company, the brewer,
the landlord, the landlady,
the slavee, the daughter,
the barrel, the half barrel,
gallon, the half gallon, quart pot,
pint pot, half a pint, gill pot,
half a gill, quarter gill,
nipperkin and a round bowl;
Here's good luck, good luck,
Good luck to the Barley Mow!
