I did explain this in one of the first postings. The acrobatic dance style. Hand on heart by 1976 barely anyone was doing this at all, apart from spins and the very occasional splits. Seriously. It reapearred when the cameras were let into Wigan and it reappears magically whenever a TV documentary is being made. Acrobatic dancers were an absolutely minority since 1976 but the impression that TV slots like this give, is that not only does everyone do it, and the ones that don't are on the perifery of the scene, but they all dress in 40 year old fashions to do it!
I have absolutely nothing against anyone dancing like this, or dressing like this, nothing, it's their choice and if it makes them happy then I am happy for them, all my complaints are about how NS is ALWAYS portrayed in the media like this. Nothing to do with any individuals or groups of people at all.
