I get to post the lyrics, after everyone has had a whole week to beat me to it? I'm amazed, and glad I can help.

From the album Gentle On My Mind:

Now August is a wicked month
Of pleasure yet so bad
Escape from all the hopes and fears
A time to laugh, a time for tears
And run away from the rest of the year
And love in the tall, tall grass.

The August sun's a wicked sun
It tans the cheek and leg
It warms your soul and body and
It stills the tiny voice within
That warns in vain against your sin
And love in the tall, tall grass.

Now August is a wicked month
It leaves the lost alone
A hand outstretched, a fleeting smile
Come hither now and stay awhile
And love will warm this lonely child
Down here in the tall, tall grass.

Now August is a wicked month
Romances spring and die
When autumn comes, the season turns
The pain of leaving starts to burn
Reality we start to learn
From love in the tall, tall grass.
