When I first heard "Columbus Stockade Blues," I quickly noticed the similarities between one verse in that song and a verse in "You are my Sunshine." In "Columbus Stockade Blues," it goes something like "Last night while I lay sleeping/I dreamed that I was in your arms/When I woke I was mistaken/I was peering through the bars."
Could it have originated with Darby and Tarlton, or was it a floating verse?
