I'm thinking of attending the challenging chorus workshop on Sunday. This stevedore tribute song by Edward J. Brady from the Sydney docks in Australia might be a prime candidate:

---------C------------------G---C
Now it's yakker, yakker, yak-ker,
------G-----C--------------G--C
For your drop o' beer an' bacca,
----F----------------------C-----------------Dm---------------F
To earn your bloomin' clobber an' the bit o' tuck you eat,
----------------C--------------G/C
When you're layin' on the screw,
-------G--C------------G--C
With the boss a-curs-in' you,
----------F--------------------C------------------G-------------------C
An' the sweat runs like a river, an' you're chokin' with the heat!

Cheerily,
Charley Noble
