I am at a loss as to what your final comment refers to.
Well, I particularly disliked the "extra beat" (or extended measure, following the ABC file) near the end of the B part (the "hiccup", as Jody has put it) right from the beginning.
Thus my very first decision had been to keep and allocate all the notes (without changing any of them) just within a regular 4/4 measure (feeling confirmed by your statement then).
My understanding of the "folk process" includes the legitimacy of such modifications (in order to personalize a tune, and even learn to like it after all, as has been the case here).
Apart from limited spreading of ones version, may fellow and future folkies decide whether to adopt them - or not.
