I've always said that the nostalgia scene and those that push this sh!te have little to do with the ethos of the real Northern Soul scene thus they don't deserve the tag and we shouldn't give it up.
But - they've won, the term Northern Soul for me buckles under the weight of fancy dress wearers, limited play lists, boot playing Djs, and now bloody dance lessons (should be able to become advanced after 3 hours me thinks ) and those who peddle this kind of tush can have it.
