I'm interested in the way that folk music is developing and being reinterpreted by today's performers like, for instance, Bellowhead.

Surely all Bellowhead are doing is making saleable product for the purposes of popular consumption & entertainment? Being Folk, of course, there is invariably an aura of attendant worthiness (often justified) but that's all part of the general aesthetic which Folkniks get off on as much as Heavy Metal types get off deathheads and busty leatherclad vampires (always justified) or the sumpuous packages, copious notes & libretto of Alia Vox CDs (likewise). No harm in this of course - after all, this is how (most) great music is made these days, but the nature of Traditional Folk Song in its Natural Habitat was a very different beast and I think one at least must acknowledge this whatever you're personal tastes might be.

But my current project goes the other way in time: research into the use and production of music in Neolithic and Bronze Age Britain.

Anything to link to on this one??
