with so many variants under the banner "northern soul" some want rare soul,some oldies,crossover etc trying to attract a big enough crowd to cover the costs. its hard to get the right formula but its the people on the dance floor that payed to be entertained and as its the djs "JOB" to keep the customers happy or no punter equals shit night and eventual closure. if it was as easy u could put a top 500 cd on have no dj and be quids in but its not its takes a good ear and knowledge to keep them entertained and return again to the venue
