Tony, with the greatest respect, you're not seriously suggesting that there were barely 20 serious reggae collectors in the world in the early 70's, are you ?
What about Australia, Germany , France , New Zealand, Canada , Japan etc around that time ?
Must say I've always found it amusing that so many on the northern scene have for so long thought that the soul music collecting world has only ever extended as far as a few counties in England ! The old "two known copies" cliche that we so often hear !!!
Amazing the number of record collectors I've come across Down Under in Oz for example who've amassed superb collections of soul music (and reggae too for that matter) over the last 40 years but who have lived their whole lives in virtual blissful ignorance of the UK northern soul scene !!! And frankly, they couldn't care less about the northern scene ....
Which is why one can't help thinking that there really must be more than two copies of Frank Wilson somewhere in the world ... it's just that those who have them apart from Tim Brown and Kenny Burrel simply don't feel the need to trumpet it to the northern soul scene ...
