Thanks MM, I reviewed the Forum and remembered that Dale Rose had found an on-line GIF at Library of Congress (or similar). I had promised to notate the tune but have not prior to this. I found the song in print in 'Irish Music Hall' from MCA/MILLS - no publication date.
Of the 70 or so songs in this volume of 'American Irish' songs there are probably three others that would warrant attention:
If You're Irish Come Into The Parlor (missing tune in DT)
Irish Jaunting Car (popular in my parent's era)
With My Shilelagh Under My Arm (music hall classic)
It also includes a number of songs that are in the DT, where authors are nominated. While I can't guarantee their authenticity I'll mention them now.
