Two by Roger Watson. No 2 Top Seam is in the DT but Invalid Miner isn't.

At 14 Jim left school
With other lads the same,
And like his father had done before
A miner he became, my boys, a miner he became.

A collier lad so bold
One of the best was he
And at the age of 45
They made him a deputy.

A deputy he'd been
For only just a year
When a gas explosion down the pit
Put an end to his career.

The doctors did there best
For a good three months and more
Until they came and told him straight
He never would see any more.

The doctors did there best
For a good twelve months or more
Until they came and told him straight
He never would walk any more.

He's on the welfare now.
It pays his children's keep,
A load of coal four times a year
And a pension every week.

But what they'll never do
No matter how hard they try
Is to give him another pair of legs
Or another pair of eyes.

I emphasise again that this is by Roger Watson, because there is a (quite possibly apocryphal) story that someone once sang it at a club where Roger was present and didn't even credit him. Roger, thinking he might innocently have thought it was traditional, went up to him at the break and asked if he knew who had written it. The reply was "Yes. But I'm not telling you. F*** off and find your own material!"
