The words are different the original (Child) version but this is a very close approximation of the song as performed by Sandy Denny.
"I forbid you all that wear gold in your hair To travel to Carterhaugh, for Tam Lin is there
None that go by Carterhaugh but they leave him a Either their of green or else their maidenhead"
tied her kirtle green a bit above her knee And gone to Carterhaugh as fast as go can she
not pulled a double rose, a rose but only two When up then came young Tam Lin, says, "Lady, no more"
"And why come you to Carterhaugh without command me? " "I'll come and go", Janet said, "and ask no leave of thee"
Janet tied her kirtle green a bit her knee And she's gone to her as fast as go can she
Well, up then spoke her father dear and he meek and mild "Oh, and alas, Janet," he said, "I think you go child"
"Well, if that be so," Janet said, "myself shall bear the There's not a knight in all your hall get the baby's name
For if my love were an earthly knight, as he is an elfin I'd not change my own true love for any you have"
So Janet tied her kirtle green a bit above her And she's gone to Carterhaugh as as go can she
"h, tell to me, Tam Lin," he said, "hy you here to dwell? " "The of fairies caught me when from my horse I fell
And at the end of seven she pays a tithe to hell I so fair and full of and feared it be myself
But is Halloween and the fairy folk ride Those would let true love win at Mile's Cross they must bide
So first let pass the horses black and let pass the brown run to the white steed and pull the rider down
For ride on the white steed, the nearest to the town For I was an earthly knight, give me that renown
Oh, they will turn me in your arms to a or a snake But hold me and fear not, I am your baby's father
And they will me in your arms into a lion bold But hold me tight and fear not and you will love your
And they will turn me in your arms into a knight But cloak me in your and keep me out of sight"
In the middle of the night she heard the ring She what he did say and young Tam Lin did win
Then up spoke the queen, an angry queen was she, "Woe betide her face, an ill death may she die"
"Oh, had I known, Tam Lin,'' she said, "what night I did see I'd have looked him in the and turned him to a tree"
