The version on Cajun Lyrics website is unassailably authentic because it's the Hackberry Ramblers version. That band has been together forever. My friend Ben Sandmel was their manager and drummer for several recent years while he was in his 40s & 50s while the rest of the group were in their 70s & 80s.
Ben recently published the definitive biography of New Orleans R&B icon Ernie K-Doe, incidentally. Can't mention his name without plugging his latest and greatest accomplishment.
