I think your somewhat tiresome views on 'crappy rare shit' cloud what could otherwise be a constructive post.
If youngsters don't know the tune, it matters not on rarity or obscurity, but moreso on tempo and danceability of a tune....they don't know the tune anyway, so it's always gonna be 'what's in the groove that counts'.
Whether that be classic motown, overplayed oldie, rare unknown, Northern, R&B or even godforbid Latin.
If its an uptempo tune that is infectious enough youngsters will dance.
Your example of Troy Dodds could be swapped with Diana Ross's 'Stormy' and the same lemon sucking theory would hold true.
Do you really believe that every old Motown or Eddie Floyd single would have a positive dancefloor reaction for youngsters, where every rare, obscure, or virtually unknown one would not.
I'd love to be able get 600 youngsters with no knowledge of 60s/70s soul into Kingshall and show just how wrong you are.....
