The words are different from the original (Child) but this is a very close approximation of the song as performed by Sandy Denny.
"I forbid you maidens all that wear gold in hair To travel to Carterhaugh, for young Tam Lin is
None go by Carterhaugh but they leave him a pledge their mantles of green or else their maidenhead"
Janet tied her kirtle green a bit above her And she's to Carterhaugh as fast as go can she
She'd not pulled a double rose, a but only two When up came young Tam Lin, says, "Lady, pull no more"
"And why come you to Carterhaugh command from me? " "I'll come and go", Janet said, "and ask no leave of thee"
Janet tied her kirtle green a bit above her And she's gone to her as fast as go can she
Well, up then her father dear and he spoke meek and mild "Oh, and alas, Janet," he said, "I you go with child"
"Well, if that be so," Janet said, "myself bear the blame There's not a knight in all your hall shall get the baby's
For if my love were an earthly knight, as he is an grey I'd not change my own true for any knight you have"
So tied her kirtle green a bit above her knee And she's gone to as fast as go can she
"h, tell to me, Tam Lin," he said, "hy you here to dwell? " "The queen of fairies caught me when from my horse I
And at the end of seven years she a tithe to hell I so fair and of flesh and feared it be myself
But tonight is Halloween and the fairy folk Those that would let true love win at Mile's they must bide
So first let pass the horses black and then let the brown Quickly run to the white steed and pull the rider
For ride on the white steed, the nearest to the town For I was an earthly knight, they give me that
Oh, they will me in your arms to a newt or a snake But hold me tight and fear not, I am your baby's
And they will turn me in arms into a lion bold But hold me tight and fear not and you will love child
And they will turn me in your arms a naked knight But me in your mantle and keep me out of sight"
In the middle of the night she heard the bridle She heeded he did say and young Tam Lin did win
Then up spoke the fairy queen, an angry was she, "Woe betide her ill-far'd face, an ill may she die"
"Oh, had I known, Tam Lin,'' she said, "what this I did see I'd have looked him in the and turned him to a tree"
