A couple of observations on Lesley's C H Ross version ...
Ross's version was acclaimed as being pretty dreadful (and thus very popular). "Muckers" is not the orignal word! "Quod" (with an "o") is slang for prison.

The tune is one of those that won't lie down. It appears in slightly different forms all over the place: Captain Kidd, Admiral Benbow, a number of scurrilous songs I don't remember from my schooldays; and there was a song called "In Mobile", which I could never tell if it was rude or not: Joe?!
