I only entered my earlier post because no one could explain where the nickname "McAlpines Fusilers" came from.
   This thread has been going for nearly ten years, with claims
of who wrote the song. I have never heard any other version than Dominic's, but recognised the tune and some bits of the verses.(see my earlier post)
I suggest He got inspiration from hearing the older versions and info. from lads who had worked on the sites mentioned in His song.
   Jim you are correct. I first heard the the first verse of Dominic's song echoing thru the Glens of County Tyrone on a cold February day in 1952.
