The ong, On The Banks Of The Old Ponchartrain, was written by Hank Williams Snr & Ramona Vincent in 1947, and recorded by Hank, you can hear him sing it on YouTube. I don't know if it's meant to be a version of Lakes Of Ponchartrain, but I'd reckon certainly influenced by it while having a different tune, and being a darn good song in it's own right
