Good on yer, Jim.
I'm including parts of Scotland when I say the north. A handful maybe but hardly tiny. The NE bothy tradition, Tyneside mish mash of older stuff, broadside ballads, music hall and industrial songs, Yorkshire Pennine tradition still going, the hunt repertoire in the north, even the Lancashire dialect and industrial stuff I understand, all nowadays influenced by the revival but continuous and still going.

And of course that wonderful piece you mention 'You'll never walk alone' has achieved traditional immortality on the football terraces and that's not just a local tradition.
