I've counted all the bricks!

"Give us a chorus, Jimmy!"

Jimmy does, giving his head a short, jerky nod for nearly every word,
and describing a circle round his crown -- as if he were stirring
a pint of hot tea -- with his forefinger, at the end of every line:

Hall! -- Round! -- Me -- Hat!
I wore a weepin' willer!

Jimmy is a Cockney.

"Now then, boys!"

Hall -- round -- me hat!

How many old diggers remember it?

And:

A butcher, and a baker, and a quiet-looking quaker,
All a-courting pretty Jessie at the Railway Bar.

I used to wonder as a child what the "railway bar" meant.

And:

I would, I would, I would in vain
That I were single once again!
