Having just watched the first of the new 'Sherlock' series I think I can understand what SRS means. I'll give it a try anyway.

Historical accuracy is as important as people feel they need. Which, as a personal feeling, is extremely subjective.

Back to the Sherlock comment I find that the stories that the beeb are currently showing, set in the modern day, are equaly as valid as Arthur Conan-Doyles originals. They are not authentic or accurate depictions. Neither are the recent films with Robert Downey. But they have something to say. It will not be to everyones tastes but they are non the worse for that.

By all means keep, enjoy and even revere the originals but enjoy the interpretations as well. There is room for all of them. I do believe I have said the same about folk song! If we insist that things must be done in the way they always have been we risk loosing a lot of creativity. Conversely we also risk some very poor interpretations. Just look at some early Hollywood histories! Anyway - How does the song go?

"Flowers are red and leaves they are green. There is no need to see flowers any other way that the way they always have been seen" Some people sadly beleive that :-(

But as to an Anglo Cocertina with a D row. An abomonation that should be cast into the pits of hell, sir! Mine is a genuine TRADITIONAL Lachenal with the middle row in C as it should be for ever after, Amen.
