Interestingly most of the titles in that list have many variations.
If you think that doesnt matter - that they are merely different words to the same tune or whatever, just listen to the three (count 'em. Three) versions of 'Paddy Doyles Boots' that are to be heard on the sound track to Moby Dick.
As hultonclint (we know who you are) points out in his foreward/more info to this shanty, it is not sung to the correct work at hand, but, the three versions are all entirely different - one version having twice the pulls of another. All three are Bunt shanties, but all three are not the same by any means.
And that is just ONE of the shanties taken from that list.
Now define which shanty was used for which job. I dare you.
