There's no doubt that this is an interesting topic James, so thanks for starting it.
However it raises questions which slightly puzzle and perplex me.
The Johnny Howard case study is particularly illuminating. In the early 80s it seemed that every record box I looked through had a copy of this disc for no more than a couple of quid. Personally I've always preferred the Artistics version, but that's beside the point. If Butch was indeed responsible for 'resurrecting' this record then fair play - it shows that he has the power to take a relatively common sound and elevate it to a status that it's relative ubiquity probably doesn't deserve.
What does this say about the scene though?
In the case of the DJ who removed your record - that's actually shocking. Name and shame, I say. I don't think I'd have been able to show the same restraint you did. I'm sure I and many others would love to know what makes him (or her) believe they have the sole Djing 'ownership' over a particular record made by SOMEBODY ELSE.
Because at the end of the day that's all it is really - whether at a high level or low level - showcasing sublime examples of Black American Music made by talented people. We're only the custodians of some of the best music ever made. We'd do well to remember that.
