It was, in the early days run by Neil Rushton's Heart of England Soul Club. What was so cool was that it brought together, the distinct differences, of the Mecca and Wigan of that time, into one venue.
You would see the Peg wearing shufflers of the Mecca dancing side by side with the beer towel, Spencer baggies of Wigan. Classic leather shoes on one and plastic sandles on the other.
As for Rafters, this was in the main, the Jazz Funk evolution, of places like the Ritz in Manchester. DJ's Jonathon, Colin Curtis, Pete Haigh and others. Also it had a much more black audience. Where as northern soul had been mainly a white working class scene, jazz funk was more cosmopolitan.
