All depends which venue you are at.
Kings Hall Stoke for instance, I can't think of a better set than Andy Dyson.
Well thought out, and even though he has mega rarities, he sacrifices his own personal thoughts for the more all nighter underplayed 45's.
At Blackpool, a different type of audience.
Yes we have hardcore but they tend to be out manouvered by a more dumbing down Top 100. I certainly have no problem with that, after all its my daytime job. But I wouldn't expose say Andy to that crowd. That's more for Chris K, Ginger who are comfortable and happy to play in the latter's case JT Parker and Julian Covey in the same set.
The scene is extremely wide now and the ones who fully understand it are getting the most bookings.
My advice to any DJ who wants to further their Northern Soul career is to look at what you are trying to achieve.
If your heart lies with unpopular but brilliant vinyl, stick to that.
But whichever path you choose, don't complain if you are at a bog standard Soul night and you get asked for The Tomangoes more than twice, because chances are you will do.
