Peter made various alterations of his own to the text as originally published in The Journal of the Folk Song Society (vol. II issue 8 1906 176-7). The text posted in the other thread (with some typos) is the Journal one, as re-printed in Dan Milner's Bonnie Bunch Of Roses, where presumably it was given with Mr Leatherday's tune.

In fact, the Journal text was only partly from Mr Leatherday. Either he didn't remember it all, or Vaughan Williams only noted down part of it (a common practice of his, unfortunately); the text was expanded from a broadside issued by F. Paul of Spitalfields.

Three broadside editions can be seen at  Bodleian Library Broadside Ballads:

On board of a ninety-eight

The song is number 1461 in the Roud Folk Song Index.
