The words are different from the original (Child) version but this is a very close approximation of the as performed by Sandy Denny.
"I forbid you maidens all wear gold in your hair To travel to Carterhaugh, for Tam Lin is there
that go by Carterhaugh but they leave him a pledge Either their mantles of or else their maidenhead"
tied her kirtle green a bit above her knee And she's gone to Carterhaugh as as go can she
She'd not pulled a double rose, a but only two When up then came Tam Lin, says, "Lady, pull 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 green a bit above her knee And she's gone to her father as as go can she
Well, up spoke her father dear and he spoke meek and mild "Oh, and alas, Janet," he said, "I you go with child"
"Well, if be so," Janet said, "myself shall bear the blame There's not a knight in all your hall shall get the baby's
For if my love an earthly knight, as he is an elfin grey I'd not change my own true for any knight you have"
So Janet her kirtle green a bit above her knee And gone to Carterhaugh as fast as go can she
"h, tell to me, Tam Lin," he said, "hy came you here to " "The queen of caught me when from my horse I fell
And at the end of seven years she pays a to hell I so fair and full of flesh and it be myself
But is Halloween and the fairy folk ride Those that would let true love win at Mile's they must bide
So first let the horses black and then let pass the brown run to the white steed and pull the rider down
For I'll ride on the 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 tight and fear not, I am your father
And they will turn me in your arms into a bold But hold me tight and not and you will love your child
And they turn me in your arms into a naked knight But me in your mantle and keep me out of sight"
In the of the night she heard the bridle ring She heeded he did say and young Tam Lin did win
up spoke the fairy 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 this I did see I'd looked him in the eyes and turned him to a tree"
