All this talk of discos / youth clubs etc.....Down in Kent our local ones, as far as northern is concerned, we had to take records along and try and badger the DJs to play them. This met with variable success, some would play 3 or 4 on the go, and others would have to be badgered into submission.
Worst one I recall was one night at the Teen & Twenty Club in Tonbridge, and I had taken down Kim Tolliver "I don't know what foot to dance on". The "guest" DJ eventually played one verse of it, then announced "that's a load of crepe" and took it off. When I collected the record back to him I told him that I thought he was a solo practitioner when it came to sex (in one word), and never to darken our doors in Tonbridge again. I don't think he did either!
My initial influence as far as northern was concerned was more radio orientated, and then mags like Black Music / Blues and Soul. I wanted to find out what all the fuss was about.
As far as mainstream soul was concerned originally got into that via Radio Luxemburg / Radio North Sea International, and believe it or not Top of The Pops where groups like the 4 Tops were omni-present.
