In my view it is important that the source material survives but I see know problems at all mixing it up with other musical forms - one of the most exciting things I have ever heard was what an artist who went under the name of Broadcaster did with samples from the original Radio Ballads. Chumbawamba also did wonderful things with samples of folk songs on their CD 'Readymades'. The more we can get folk music, in any form, out into the wider community the more likely we are to attract new people into discovering the source material and maybe even becoming folkies themselves.
