A guy on eBay that regularly lists these pressings/re-issues with stuck on labels won a couple of 'proper' 1970's vintage pressings off me recently, I am now expecting them to be auctioned off very soon with freshly printed labels and see him get back three times his original investment.
He is very honest (if you can call it that) about what he is selling, so I won't make further comment on that side of things.
I doubt that I am alone in this, but when I was regularly attending venues in the 1980's and 90's, part of the thrill for me was being in the same room as those rare pieces of vinyl that the DJ had spent a lot of time and money tracking down to play for our listening and dancing pleasure.
I'm now struggling with the idea that there are 'imposters' going up and down the country, carrying boxes of mocked-up 45's to play to the paying punters. Come to think of it, I attended an event last year and every now and again, the sound quality off some of the records seemed suspiciously poor, so I guess I may have been an unsuspecting victim of someone spinning a few boots here and there.
Maybe I'm just over sensitive, I felt terribly cheated when I found out that Jools Holland's Annual Hootenanny wasn't a live broadcast and was actually recorded in October...
