Are you going to Scarborough Fair?

Parsley, sage, rosemary and thyme, Remember me to one who lives there, For once she was a true love of mine.

Have her make me a cambric shirt, Parsley, sage, rosemary and thyme, Without a seam or fine needle work, And then she'll be a true love of mine.

Have her wash it in yonder dry well, Parsley, sage, rosemary and thyme, Where ne'er a drop of water e'er fell.

And then she'll be a true love of mine.

Have her find me an acre of land Parsley, sage, rosemary and thyme, Between the sea and over the sand, And then she'll be a true love of mine…
