There is no such thing as "The wrong lyrics to a folksong"For instance," Greenland Whale Fisheries", The date is usually in the first verse, therefore it's easy to follow this one through the folk process. Anyone who thinks that time and usage don't improve on the "original" just follow this one through the process. I pretty much sing the version that starts, "In eighteen hundred and sixtty three on June the thirteenth day,our gallant ship her anchor weighed and for Greenland Bore away BRAVE BOYS for Greenland bore away."
Compare that with the earlier versions. Which one is better poetry? My contention is that anyone who would prefer the "oldest" version of this song to more current ones has his (or her) head up his (or her) ass.

You make up your own mind. If anyone complains about your choice, just tell them to "go piss up a rope". If it's a woman, this is extremely hard to do.
