For what it's worth, I've learned to live with Hugill's style of bowdlerization. I've tried to look at it from the standpoint that in many (most?) chanteys, the verses/ lyrics were variable/optional. The "professional" chanteyman would be able to make his lyrics as clean or as dirty as he wished, at the moment. I get the feeling that even if I were to see the supposed "uncovered" versions of all these songs in print, I would still view them with suspicion because I could come up with something way more dirty!....and if I could, I'd suspect that some singers did. Otherwise, I'd be forced to admit that my mind is more debased! I am mostly kidding here, but there may be something to this, about what we view as obscene and why leave certain things unsaid.
Many of the earlier collectors printed only 1 or 2 verses on the grounds that there were no set verses, "so why pretend to set them down?" That being said, I am glad for all the variety of verses that Hugill gives. I agree that he is a tease, but at least he often provided rhyming equivalents or double entendre so you can guess, as opposed to wholesale bowdlerization.
I can deal quite well with "ringtailed black man sheet it home behind," but I really dislike "your pigtail, sailor, hanging down behind"!
