The record dealer was probably just talking bollocks, dealers are well known for all this 'nudge nudge wink wink' stuff, especially NS dealers, they are the worst at talking in riddles and testing people's knowledge when half the time they are just regurgitating nonsense. I dread it at fairs when I start looking through the records of a 'talkative' dealer. You know the sort, inevitably they start providing a running commentary on any record you look at for more than one second - 'well you know who that really is don't you'...'of course you know the story about that one don't you'...nudge nudge wink wink...
