The version I used to sing was;

I found an old stocking, I filled it with lead
I hit an old lady right over the head.

Along came a copper and asked me my name
I told him ploitley with a bycycle chain.

I judge said sit down boy and wipe up your tears
Your going to borstal for the term of three years.

My mother was crying mysister was too
My father was laughing and so was the screw.

I counted the moonbeams I counted the stars
I counted ten thousand behind borstal bars.

I dreamt I was warden and the warden was me
I iopened my cell door and set myself free.

But I'm not the warden and the wardens not me
so here I stay for my term of three.
