Ok I'll say my bit now the missus has said hers,,,
First if its in the groove that counts then there is no such thing as an oldie, modern tune , cross over or what, because all that counts is in the groove, secondly if its all that is in the groove, why do people run 'oldies nights' and advertise them as for 'soulies only' as if they are the only people who know what soul music is.
again there is no such thing as an oldie because just about everything we play is old and when we went to our youth clubs and early soul nights weren't we in fact listening to modern music????, well we didn't know what it was and we had never heard it before, so at best it had to be crossover.
No, oldies are to do with nostalgia and going out and listening to them again is a nostalgia trip. To be true to northern soul you have to remember what northern soul was about and that was discovering 'new music' rare and obscure records, the rarer the better. That remains for me the heart of northern soul. I love my oldies and I do like to hear them but going to some soul nights is like listening to the oldies radio stations.
We can keep the oldies (played out tunes) but we need to rediscover some of the excellent oldies never or hardly ever played whilst remaining true to the desire to discover new music.
