There is a load of music out in the world which gets called folk or people call folk because they are not able to think of another label

Yes, it can be defined generally as:

(a) stuff composed in their bedrooms by angst-ridden teenagers who once lived next door to someone who once owned an acoustic guitar, and they have emerged, convinced that the world owes them a living, and

(b) pseudo-celticky, wifty-wafty new-agey crap.

What about (to wildly embrace all there is): 'music from out there rooted in a tradition) as a definition?

SoH consists of a really good multi-instrumentalist, Phil Beer, who has been involved in many excellent projects over the years, and Steve Knightley who is quite a good songwriter. I find what they do together very bland but, presumably, it pays their bills.

Martin Joseph might please some but to me he's a god-obsessed crooner. There's an awful lot of under-represented Welsh trad out there (Twm Twp, Bragod, Julie Murphy, Mary Humphreys for starters . . . )

Where would we be without Mike Harding? To be fair to him, if he was a BBC (i.e. PSB) presenter with some say in programme content (as opposed to a puppet for an outsourced production company), he might be SOME use. As he's not he's best ignored. BBC R3 is the only place to hear folk music: Late Junction, Andy Kershaw and World Routes.
