Julian Cope presents Head Heritage

I've got to say I have never understood why ultra-limited editions are released - unless they have expensive to produce packaging like wooden boxes etc. I mean - who is this benefitting? Not the artist, because he won't sell many copies. Not the hardcore fans, because they are forced to pay through the nose to EBay/Discogs sharks. It must just be a vanity thing - being able to say "my single sold out straight away" even though it only sold 50 copies.
At least this single doesn't have an exclusive b-side - that really would be a cuntish thing to do.
