Were Michael Parkinson's ancestors coal miners? Hard to make an interesting story there I imagine.
An industry that goes back to Roman times. The engineering, the industrial revolution, the fight to end child labour (particularly after the Huskar disaster, which happened not far from where Michael Parkinson is from), the Royal Commission into conditions. The well documented stories of the women who worked in them, the 'pit brow lasses'. The rise of the trade unions, the evictions of miners and their familes, and the lock outs. The general stikes (1842 and 1926 in particular), the last miners strike 1980s...
WDYTYA are not interested in English working class history, so don't expect any middle class BBC tears and handwringing over the turnip pickers, the industrial spinners and weavers, the coal miners, or the hawkers and chimney sweeps. It will be off on the jollys again, to India, Ireland Jamaica, and so on. Rinse and repeat
