If you listen to the Wigan tapes from 79, 80, 81 there are masses of modern things being played, sometimes off 12" ers that last 20 minutes, bloody horrible things like Omni and Rosey Jones and Larry f*cking Houston, the 70's gems like Will Power are few and far between and I just stopped going so I didn't have to hear this sort of crap. And I still won't go anywhere that plays it, that is not what Northern Soul is about to me. Meanwhile, both I, and you if you stopped going, missed Richards fantastic new 60's discoveries around that time, and there are loads of them...but they still mixed them in with the 70's and I do not believe that it works.
Wonderful world of modern soul? Do me a favour. Keep it separate from the proper music.
