Two come to mind, both from the North east of England. The first is usually called "SAIR FYLED HINNY" or some other such attempt at the dialect. I have never seen it written without an attempt at the dialect, so I won't break the tradition:

Sair fyled, Hinny
Sair fyled noo
Sait fyled, hinny
Sin' I kenned thou!

I was young and lusty
I was in my prime
I was young and lusty
Many's the lang time

Sair ...

When I was five and twenty
I was brave and bold
Now at five and sixty
I'm baith stiff and cold

Sair..

Thus said the old man
To the oak tree
Sair fyled am I
Sin' I kenned thee!

(a rough translation of the chorus in plainer English: Greatly failed am I, friend, since I [first] knew you)

The second is THE HEWER, which I've heard from Louis Killen:

When I was young, and in my prime
Ee, aye, I could hew!
I was hewing all the time
But me hewing days are through, through
But me hewing days are through.

I've lain down flat, and I've shovelled coal
Ee, aye, I could hew!
And your eyes did smart in the dust-filled hole
But me hewing days are through, through
But me hewing days are through.

...

Its soon no more the pit I'll see
Ee, aye, I could hew!
But I'll carry it round inside of me
But me hewing days are through, through
But me hewing days are through.

There are some of the middle verses missing in that, but I forget them for the moment
