I was in a band for a while that did an original song called Lammas Night loosely based on the Burns poem...careful it is a bit racy! ;0

Lammas Night

The grain was reaped, the bins were full
The country danced, I with the Harvest Queen
She took my hand and led me through the night
Among the rigs of barleycorn

Chorus:
'Neath the rigs of barleycorn
Come, my havrest queen, and lay with me once more
And let me taste the honey of your love
Among the rigs of barleycorn

She came to me on Lammas Night
I lay with her and nested in her down
The moon warm and full caressed her swollen breats
Among the rigs of barleycorn
Chorus...

The newly-turned earth became our summer bed
My heart cried deeply for this night to never end
As she took me down within her rounded thighs
Among the rigs of barleycorn
Chorus...
