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…
