Each campfire lights anew
The flame of friendship true
The joy we've had in knowing you
Will last our whole life through

And as the embers die away
We wish that we might ever stay
But since we cannot have our way
We'll meet again some other day

We usuallly followed this song with the singing of TAPS - of course with our hands folded in front of us and grasping the hand of the scout next to us in the circle.
Enjoy
