Bounty Hound sent me a message via facebook to which I am now posting a response. The song I sing is called The Amazon and it's not the one you're looking for. For some idea of the range of texts of this song look at the Musical Traditions website - go to the Dungbeetle contributions and look for a set of observations on "The Spanish Snow" - there are also some versions on the Bodleian Ballads website.

Also, for the Little Fighting Chance or the Fourteenth of July, (Laws J19) if you go to the website of the EFDSS the Roud index (no 980) contains versions other than the one from Broadwood - Greig-Duncan vol 1 p 91 and MacKenzie Ballads and Sea Songs from Nova Scotia p 215. It also shows an article which cites the song from Broadwood - Journal of the British Archaeological Association. 42 (1886) 310-312 - there might be some background - I may be able to source the article if you have difficulty. I have access to all the versions mentioned and none of them has any accompanying note that might help.
