We lived for thirty years a couple of miles from Eastwood - the birthplace of DH Lawrence. The accents in that area are every localised. My wife was from Heanor, Derbyshire - about four miles away and another set of spoken inflexions in the speaking voice.

We always used to laugh at RADA all purpose northern accents trying to negotiate the subleties of Lawrence's dialogue - often completely misunderstanding the nuances.

And of course Derbyshire folksong is a set of linguistic beartraps for the unwary. And who knows in ten years, maybe no one will pick up the nuances - certainly not in a hundred years.

Still, the actors got Oscars and some of the folksingers made livings and got great reviews for their albums - and thousands of people got enjoyment from those performances. So what the hell does any of it matter?

Most of the so called purists couldn't tell talk from mutter anyway.
