I guess I might as well throw in another version, transcribed from the singing of Ian & Sylvia. This is the one I learned 40 years ago to be sung a capella, preferably with at least one harmony singer complementing the lead.

Greenwood Sidie
(from the singing of Ian & Sylvia)

There was a lady lived in yore
Comely and lonely
Fell in love with her father's clerk
Down by the Greenwood Sidie – o

She loved him up, she loved him down
Anna-lee and loney
Loved him 'til he filled her arms
Down by the Greenwood Sidie – o

She leaned her back against an oak
Anna-lee and loney
First it bent and then it broke
Down by the Greenwood Sidie – o

She leaned her back against a board
Anna-lee and loney
There she had two fine babes born
Down by the Greenwood Sidie – o

She took out her reapin' knife
Anna-lee and loney
There she took those sweet babes' lives
Down by the Greenwood Sidie – o

She wiped the blade against her shoe
Anna-lee and loney
The more she rubbed the redder it grew
Down by the Greenwood Sidie – o

She went back to her father's hall
Anna-lee and loney
Saw two babes a-playin' at ball
Down by the Greenwood Sidie – o

Babes, oh babes, if you were mine
Anna-lee and loney
I'd dress you up in scarlet fine
Down by the Greenwood Sidie – o

Mother, oh mother, when we were yours
Anna-lee and loney
Scarlet was our own heart's blood
Down by the Greenwood Sidie – o

Babes, oh babes, it's Heaven for you
Anna-lee and loney
Mother, oh mother, it's Hell for you!
Down by the Greenwood Sidie – o

I first heard this one early in my college career when I was just being introduced to a lot of Anglo-Celtic folk music that I hadn't heard before. This was probably the most haunting song of the whole lot that I was introduced to at that time.
