It's actually a comment made in jest Paul and I agree with many points you make in your original text above. As I think readers may be able to imply, rather than me explicitly state, I find the whole Northern Soul dance class thing a bit cringy. The references to the fictitious 'Soul Police' and 'original' are again used in humour, maybe I should have used a smiley at the end of the sentence .
Perhaps we were lucky getting into the scene when we did (me personally North Wales attended many venues after the Casino closed - never went, my period actively on the scene 1982 - 91 Stafford, Morecambe, Parr Hall Glenrothes, Bradford, Keele etc - and do try and attend when back in the UK) as there was always the Youth Club, School discos, etc where we could go and practice and learn to develop our own individual dance styles...and of course our front rooms/bedrooms. For newer people coming onto the scene today maybe there is a need for such Dance Classes as where else to practice, and maybe these dance classes are not an attempt at commercialisation of the scene - but personally, I can't help but be a bit cynical of them. I hope that puts my original comment into a clearer context. Cheers
