Hmmm ! Since my first post on thi thread I have done a tad of digging.

Research on the other BBC Wales regions shows no specific cattagory for folk, South West wales throws folk in with giggenerally, and the Holly Bush at Pontedawe features.

There is a BBC local listings page, town by town or sub region by sub region
Viz - http://www.bbc.co.uk/events/livemusic/classical/index.shtml?rid=&ndd=&cl=default or Click 'Ere

This lumps folk with classical etc. and a sketchy random sampleing shows no great mass of folk info.

I think 'Catters are betters served by Jon Freemans site above, or Mr Reds efforts but you never know, send the details to the BBC and we may create a demand.
