Just so that you know that I'm not merely wasting your precious time Martin, I am revising my book (pub 2013) on the Civil War in Co. Waterford. I was trying to ascertain if that song had any popularity during that era, or in the aftermath. I know that my own father was in the Volunteer Reserve, I have his docs, dated in the 1930s.
I'm afraid that I cannot remember what the title was except to say that it probably was a, slightly, comic song, and I believe that the record may have been issued by the Columbia Label (Purple in colour) ? There was the other side of the disc that might have had a little "sketch" about a character called "Casey" on it. We also had a few other records with sketches about "Casey" all by the same artiste. I don't know if that is any help ? That's all I can remember.
