A bi of thread creep here but going back nearly nine years to a post about The Bullock Smithy, The programme was part of the Ballad of the Northwest series which was a BBC Northwest production for local consumption when other areas around the country had their own regional programmes. The programme in question was called "The Great Lead Rush" and the Radio Times listing for this programme is as follows.
Ballad of the Northwest

Tuesday 7th August 1973 BBC1 10:15pm Colour

The Great Lead Rush

The Story in music and song of fortunes made and lost, miners brawling in the streets, battles underground not in the Yukon but Derbyshire during the boom years of lead mining in the 18th century.

Narrator Harry Boardman

Music Bullock Smithy

Producer Douglas Boyd

BBC North West

Sadly all that remains of the programmes are some audio recordings made by pointing a microphone in front of the TV speaker and not very good quality, some scripts and various notes which I've put here Harry Boardman Facebook page (Sadly not the Great Lead Rush but I'll check my audio tapes when I get home.)
