Parts of 'Brassed Off' also filmed in lovely Halifax (!) & surroundings (which really are lovely - God's own county...), in particular one scene in the Piece Hall (used to be for the old cloth markets, hence the name; now often used for general markets or open air concerts)

And anyway, dying out it most certainly is not! Colliery bands (or rather ex-colliery bands, mostly) are still well loved and cared for in Yorkshire at least, and probably many other places. Not just for what they are and the music they play (colliery band music on a wet night, still feels like magic) but for what they were and for the lost livelihoods of the miners and their families.
