Thing is, if festivals elsewhere book acts that approximate more to pop than to folk then you'll see more Cambridges. I spoke to one festival organiser who admitted that, having spent the bit bucks to get a headline act (pop orientated and a darling of BBC2) they completely failed to deliver the host of smaller names that actually do the real work at a folk festival. There are plenty of performance opportunities for pop music but relatively few for folk I hope festival organisers start to get the message in these financially pressured times.
