The song that the two Sues refer to is also called "Love & Freedom" by some. I thought it was "hey, daughter, ho, daughter too!" ;-) Ah, Mondegreens!

The one verse I've also heard as -

I have naught to offer you/this young man said to me/but you'll gain love & freedom/if you'll come away with me

small variations, but avoids the ookiness of "my dear," (which I don't like except in parody - just a personal thing).

I *think* that 'Farewell to Tarwathie' is in the Judy Collins songbook.

Connie Dover of Scartaglen does a beautiful song called "Somebody" which technically doesn't come under this heading because it is a Jacobite lyric, but I think it could be lovely if harmnonized.

Another haunting song, though composed & not traditional (though becoming somewhat so) is 'There Were Roses.'
