" by Leadbelly has a line that goes:If you're ever in Houston, well, you better do the right
The opening line of "If You Ever Go To Houston" goes:If you ever go to Houston, better walk right
While neither Dylan nor Hunter have commented on a connection, it's doubtful the similarity is just a coincidence. Both men were scholars of American music, especially folk and blues, and frequently alluded to old songs (or just straight-up took lines and melodies from them) in their own music. Even if the line arose subconsciously, there's no way they wouldn't have immediately recognized its origin.
