Mr Burton and the Ojibwe songs

I've been thinking a little about the story I posted earlier today and there's something about it that intrigues me. Perhaps I'm over-interpreting but, to me, there's a suggestion that Burton wanted the Ojibwe singers to like his harmonised version of the song. I suppose he might have viewed what he was doing as an experiment and nothing more - a piece of research on the attitudes of a 'primitive' people. But I sense just a hint of anxiety in the air as the second version of the song begins: it seems to matter to Burton at more than just an intellectual level how the 'owners' of the tune will react to what he has done.
