Yes I think it's closest to version 1, too.I think she sings
Down the moor and among the heather
Over the moor and through the heatheras part of the chorus (followed by the last two lines of the preious verse and down the moor).
She also at one point sings about 'a plaid wrapped neatly round her waist' - although it always sounded to me like 'bladderwrack neatly round her waist'. Why she wanted this seaweed with herall time we can only guess, unless it was a portable weather forecasting system!
