Kev, you are a business man & it appears you are quite successful. You saw the re emergence in popularity in Northern Soul & saw a market to be exploited financially.
You have successfully turned Northern Soul into a brand & you sell that brand. To sell a brand successfully & for it to be financially profitable, in a business sense, the brand has to appeal to the broadest possible & largest market. Thats what you do & you do it well.
I have no problem with a promoter making money from Northern Soul if they are genuinely promoting the music for the good of the scene, but IMO the only reason you have anything to do with the scene now is because it is your living, if you had seen the window of opportunity else where, thats were you would be, its a business to you, the moment that it stops being profitable you will move on to some thing else that is. I do not know some of the promoters you have mentioned, however, of the ones I do know, they do it cos they love the music with a passion, & they want to share the music with like minded people, if they make a few bucks then great.
There are at least two scenes, the oldies orientated, nostalgia driven scene is your main market. They love your promotions, you give them exactly what they want & they love you for it, a lot, not all are in the main returnees, they know no better, probably dont even care, however the die hard, bed rock of the scene, who still see the scene as a precious thing to be nurtured & driven forward, (as much as we can in this day & age) can see exactly what you are doing & sometimes become frustrated at you for it. Its not that you are financially successful with it, its the watering down & the selling off of something they hold dear.
Hope I have been able to articulate my thoughts in a non argumentative way, I just wanted to state the facts as I see them.
