Re the spelling of branle/brawl - I prefer to use the English spelling, which has been around for several centuries, and fits with the way we pronounce it in English.

But the tune itself is the important thing. I learned it first as an entirely major tune, including the C part (maybe it was a melodeon player who led it?). I prefer it that way, but accept that I may be biased and that most people seem to like the minor key-change.
