You can hear Johnny Horton sing SLEEPY-EYED JOHN at YouTube

I agree that it sounds like "Caney Creek" & "Caneyville." There is a Caneyville in Grayson County, Kentucky, with a Caney Creek nearby, but I can't find any Candyville.

Also, Horton sings a couple of lines differently than Neil Rossi's lyrics.

"The raccoon left and the old hound whined."

"The goose he flopped but he couldn't get loose."

Also, he sings the verses in a different order (not that it matters).
