The text given by PW Joyce for "The Spalpeen's Complaint of the Cranbally Farmer" is almost exactly the same as Frank Harte has for the Galbaly farmer. Joyce says he remembers the song since boyhood and has "a copy of 'The Cranbally Farmer' on a roughly-printed sheet. This same 'Cranbally Farmer' - the man himself - was well known in the district sixty years ago as a great old skinflint; and the song drew down on him unicversal ridicule."

"Sixty years ago" would have been around 1850.

Joyce explains that spalpeens were labouring men "who travelled about in the autumn seeking employment from the farmers, each with his spade, or his scythe, or his reaping-hook. They congregated inthe towns on market and fair days, where the farmers of the surrounding districts came to hire them. Each farmer brought home his own men, fed them on good potatoes and milk, and put them to sleep in the barn on dry straw - a bed - as one of them said to me- 'a bed fit for a lord, let alone a spalpeen.'"
Spalpeen is spelled "spailpín" in Irish, and I believe the song "An Spailpín Fanach" is on Mudcat, as well as a translation of The Whistling Gypsy with the same title.

The towns in the last verse are, says Joyce, in Counties Tipperary, Cork and Limerick. naygur is a niggard, a stingy person.

Where Harte has "It would give you the trotting disorder." Joyce has "Your stomach 'twould put in disorder" and writes "This line, as it stands, wants the vigour of the original, which it is not desirable to reproduce here in its naked simplicity.")
