This song was written by Sleepy John Estes back in the 30's and recounts how he fell into the water from a bridge either intentionally by someone else or accidentally. It never resolves that question. He was rescued by a musician friend where he was taken to a home and revived. Several musicians have played this song over the years most notably Eric Clapton and Greg Allman. I personally prefer the Allman version of it as well as the original.
