I found this lurking about in my archive - it contains the bits used by Simon and Garfunkel as well as the woman's reprise. I believe this is the traditional version.

Are you going to Scarborough Fair?
Parsley, sage, rosemary & thyme
Remember me to one who lives there
She once was a true love of mine

Tell her to make me a cambric shirt
Without no seams nor needlework

Tell her to wash it in yonder dry well
Where ne'er sprung nor drop of rain fell

Tell her to dry it on yonder thorn
Which never bore blossom since Adam was born

Now he has asked me questions three
I hope he will answer as many for me

Oh, will you find me an acre of land
Between the sea foam and the sea sand

Oh, will you plow it with a lamb's horn
And sew it all over with one peppercorn

Oh, will you reap it in a sickle of leather
And tie it all up with a peacock's feather

And when you've done and finished your work
Come to me for your cambric shirt
