Not that it is very old history, but at Peaceful Valley Scout Ranch, in Colorado, a boy scouts facility, the staff sing a round of "Rose/ Love/ America" to close campfires:

Rose rose rose rose
Shall I ever see thee wed?
I will marry at thy will, sir
At thy will

Love love love love
Love is the gospel of the world
Love thy neighbor as thy brother
Love love love

America America
How can I tell you how I feel
You have given me many treasures
I love you so

Each verse is sung through in that order, and then the group breaks into 3 parts, and the last line of the last verse, "I love you so" is sung by all in the 3rd time through the round. I introduced a 'Peace' verse a few years ago, from a girl scouts' songbook, but it hasn't caught on.

Peace Peace Peace Peace
Wars will come and wars will cease
We must learn to live with each other
Peace peace peace

I've no idea where this verse came from, though it obviously stems from the one mentioned above.
