I walked through this burgeoning cornfield last week, and I thought - 'The Corn is Green' - which appears to be the title of a 1938 play by Emlyn Williams.

But also, I found this:
The corn was springing fresh and green,
and the lark sang loud and high.
And the red was on your lips, Mary,
and the love light in your eyes.
(Broadside Ballads)
