Country Music Song - Passing on a good deed.

[mike823367]

Some years ago I heard, on a Florida Country Music station, a song about passing on a good deed. Essentially, someone helped a person in need, who in turn helped somebody else, and so on. Eventually the chain came back to the original Good Samaritan, who was himself in need of help. Does anybody recognize this theme? If so, what was the song, and who was the singer?
