The recording I have of Uncle Bud sung as a zydeco song by the late Boozoo Chavis is even cleaner than the one reported in this thread by guest.xf. Using his notes and listening to the recoding over and over, here's what I hear:

   Eighteen, nineteen, twenty years ago
   Uncle Bud beat the devil outta Cotton-Eyed Joe
   Uncle Bud!

   Some people say Uncle Bud is dead;
   But that's a damn lie; he's sick in bed.
   Uncle Bud!

   Uncle Bud got a daughter, her name is Roan.
   Body like his daughter, make an old man moan,      (My best guess)
   Uncle Bud!

   Uncle Bud got cotton ain't never been picked,
   Uncle Bud got corn that never been shucked,
   Uncle Bud got a daughter ain't never been touched,
   Uncle Bud!

   Big fish, little fish, climbin' up the water,
   Some son-of-a-gun done court my daughter,
   Uncle Bud!

   Down in Louisiana where the grass grow green,
   They got more women than you ever seen,
   Uncle Bud!

   Uncle Bud got this, Uncle Bud got that,
   Uncle Bud got a big old cow-boy hat,
   Uncle Bud!

   Jimmy come up with a pack on his back,
   He bring more cotton than he can pack,
   Uncle Bud!

Now if only I could figure out the music. Anyone have it?
