It's a bit sad when I can't call an attractive young woman less than half my age a "lass" without being labelled as "pathetic". Not that I actually did or was..... but I could have done, quite naturally. In the North East, the term "lass" is not actually linked to age. Or it wasn't when I lived there, and I call my wife "lass" at some times without either of us considering her in the slightest demeaned by it.

It seems that here we have a case of dialect language use being mistaken for something else, with a strong tone of political correctness where it is neither political not correct. Any such misuse is to be opposed, wherever found.

However, whatever their true range of musical abilities, the Winterset, particularly the Unthanks, do use their youth as part of their image and performance. Therefore it is justifiable to use "young" terms when describing them, providing comment is not restricted to that, as though there was nothing more to say.
