Well, I love anything the way Nana Mouskouri sang it. I actually have always sung this changing it a little myself, because when the lyrics are first person male, I usually look for a way to have it make more sense for a woman singing it. Here are my slight changes for when I sing it:

His young love said to him,
My mother won't mind,
And my father won't slight thee,
For your lack of kine,
And she stepped away from him,
And this she did say,
It will not be long, love,
Til our wedding day.

She stepped away from him,
And she moved through the fair,
And he watched her fondly,
As she moved here and there,
And then she went homeward,
With one star awake,
As the swans in the evening,
Move over the lake.

Last night she came to him,
Her ghost came in,
She came so softly,
That her feet made no din,
And she layed her hand on him,
And this she did say,
It will not be long, love,
Til our wedding day.

So, not much different from the other version, but if you are a woman, better than singing words written for a man.
