Yes I get that, but where I am floundering is the responsibilities of the collector to his informant, and to his readers or listeners if it's recorded. Do what you want with the songs after the original is fixed, and thus keep winding the clock. For the record Berts translations and rewrites were masterful Bloody Gardener Twa Magicians etc. that's not dishonesty, its art, however some of his other actions seemed to me at the beginning of this thread, strangely out of character. I'm still a bit adrift, but reassured by the posts here. Just trying to make sense of it all, hence the 'Stalinist' question above.
