I learned this from the Girl Guides in the early sixties:

"We're all dahn i' t' coil oil weer t' muck clarts o' t' winders
Wey've used all us coil up an' we're reet dahn ti t' cinders
When t' bum bailiff cums rahnd 'ere, 'e'll niver find us
Cos we're all dahn i' t' coil oil weer t' muck clarts o' t' winders.

We are all down in the basement where the dirt accumulates upon the casement
We have used all our anthracite and we are down to the residue
When the company representative calls round here, he will not find us
Because we are all down in the basement where the dirt accumulates upon the casement.

Repeat first verse LOUDLY."
