Apparently it's from 'The Dead'

THE LASS OF AUGHRIM

If you'll be the lass of Aughrim
As I am taking you mean to be
Tell me the first token
That passed between you and me.

O don't you remember
That night on yon lean hill
When we both met together
Which I am sorry now to tell.

The rain falls on my yellow locks
And the dew it wets my skin;
My babe lies cold within my arms;
Lord Gregory, let me in.

There's a bit of info here, and I got the link to the words from this site.

Do you remember if there are any more words?
