I am well aware of that Steve- I just can't stand the schmaltzy, pseudo trad of Ms Rusby- I admire the way she and her family have harnessed the celeb culture to make pots of dosh out of the tradition. I'd apply this admiration to the Unthanks & Liza Carthy as well, both of whom have what you class as ??'traditional' backgrounds.
I just think that all three 'acts' are b... awful & little to do with the tradition, which will survive despite them.

I am also well aware of Fred Jordan's ability to pick up songs from the revival, and met the man many times, and there's nothing wrong with that- he added songs to his repertoire, he didn't INVENT one from scratch.

I will not give my name because I do not want to be pilloried by 'folkies' in this context, as I have learned that such people are blinded by the glamour of this branch of 'pop' music and unable (& maybe unwilling?) to see through the Emperor's New Clothes.
