I have no idea where Barges originates but I used to sing it at Camp Cahinnio in Arkansas... this was in th 90's and now I sing it to my baby girl to help calm her down. I'd been looking for the lyrics for the first verse because I couldn't remember all the words.

We used to sing it on the last night as we sent our candles on little pieces of bark out onto the lake. And then we'd sing Linger.
