"the cream of British folk music",.That is just a marketing ploy, and is a subjective opinion of one person[ the person who wrote the blurb,who may or may not have much insight into the British folk scene, AND IS OF COURSE ENTITLED TO THEIR SUBJECTIVE OPINION]but that is all it is, a subjective opinion of one person who may or may not be well informed.
   much as I agree with BRAGGS Political views, he does nothing for me as a performer[I would not classify him as the cream of British folk music]of that particular genre i prefer bailey or rosselson,
That is my subjective opinion, based upon being involved with the British Folk scene as a professional performer for over 35 years.
however if we all liked the same thing life would be very boring, apart from Bragg I found the other performances very interesting, and would agree with will flys comments about folk background
