Big Bertha worked in Merthyr,

Glyneath and Aberdare;

She also did Pontypridd,

Hirwaun

• • and anywhere.

You'd be forgiven if you thought

She earned her pounds and pence

Buying/selling stolen goods

- That Bertha was a “fence”.

I'm afraid though you've misheard;

She's known to local studs

For local volunteering work

- She handles swollen goods.
