I thought our anonymous initial GUEST was referring to Tam Lin (Child 39, recorded by both Steeleye and Fairport):

O I forbid you, maidens a',
That wear gowd on your hair,
To come or gae by Carterhaugh,
For young Tam Lin is there.

There's nane that gaes by Carterhaugh
But they leave him a wad,
Either their rings, or green mantles,
Or else their maidenhead.
