I was just looking at a web site which had for sale old LP records with prices attached.There was only a few old folk records, but they seemed to be four or five times more expensive than pop.       A couple of examples "Swarbrick Carthy and Disley, Rags reels and airs .....£35......Alex Campbell and friends....£40..                  My collection must be worth a fortune.....Start digging Mudcatters.
