This is a place I can immerse myself for hours & love it, but it's playing hell with the old folk process of singing things as you've mis-heard them, and passing them on altered. ;) From the Dubliners, after straining my ears, I took the third verse as:

Long years ago, when men were men, and fancied Maeve Long,
Or lovely Becky Cooper, or Maggie's merry one...

But since it's mentioned that these other girls were real people, I suppose I have to straighten out & sing right...

Always did wonder about the "heart of the roll" tho, nice to finally understand that.
