Dick, the answer to your question is in my reply: The existence of DG's version doesn't negate LBs or make it disappear. - i.e. the existence of modern or even 'commercialised' versions of traditional music doesn't make the original (if there is such a thing) disappear. It still exists - and, actually, it might get brought more to people's attention by the newer version.

You can't do a disservice to music, no matter what you do. It exists. It is. It may get obscured sometimes by history or by temporary lack of interest, but it's still there. And all taste is totally personal - you can't legislate for it, except in totalitarian states.

Why worry about it? You asked the question. That's my answer - for what it's worth!
