Chalky,
I assume you mean me . Although I have no idea who it really is, mostly because of my shocking memory. I was once told who it was by somebody, and by the morning had forgotten I've done that with several other records as well, I must start to write these things down
However, if a record really is rare, why not uncover it ? It's not as though copies are going to suddenly turn up in quantity. Look at the Mello Souls, Parliaments and Tommy Tate singles. A few have surfaced, but not enough to call any of them common, or any less in demand than they were. Just because people know who an artist really is doesn't mean they are going to find a copy. So the DJ / collector who originally found and played the record will still receive all the credit and kudos for doing that.
As a DJ I also understand why DJs want to have exclusives, but again, if it's really rare, they would still have that exclusive. Put it this way, if great record hounds like Butch and Andy Dyson have only turned 8 copies of Belita Woods up in a couple of years, how many more would other people have found if we all knew who it was. Approximately zilch I suspect !
Same with the Mello Souls, Butch had it covered for ten years, and despite knowing what he was looking for never found another one as far as I know in that ten years. Shifty found it by chance, he didn't know who the original artist was at all when he found his copy. How many have turned up since ? Two ?
And it's not as though you can claim that records are covered up to stop the bootleggers either, because if it is really rare they won't find a copy to bootleg anyway.
So really the only way to stop people uncovering cover ups, because it is a game in itself, is to not cover them up in the first place.
