Yeah, Judy's Much too much trouble is a real classic. Like someone before, we used to sing Silver in the stubble like it was somewhere in the future but reality has caught up with most of us old folkies so," If any girl would have me, she'd only have to say. I'd hang my halo on a hook until another day". Other little rhymes come to mind.
I think I'm getting older
My pilot light's gone out
What used to be my sex appeal
Is now my water spout
I used to get embarrassed
Trying to make the thinjg behave
For early every morning
It would stand and watch me shave
But now I'm getting older
It sure gives me the blues
To have the thing hang down my leg
And watch me shine my shoes.

A mate of mine's father also wrote this when he was in hospital, shot up during WW2.At least I think he did.
For the last fifty years I've been buggered
With All sorts of horrible pains
From piles and flaming great ulcers
To stitches and varicose veins
I spend all my time at the doctor's
Or lying in hospital beds
And the stuff that I took for my stomach
Has ripped my poor backside to shreds
I've got terrible pains in my backbone
I've got bunions and corns on my feet
And the stones that come out of my kidneys
Are like flamin' great lumps of concrete
But I guess I"ll just have to keep living
Despite increasing pains in my head
But my friends often shake their heads sadly
Saying,"Time the old bastard was dead"

(I should point out that bastard is officially (as inh tested in the courts) a term of endearment in Australia
