I'm trying to find out when the song Gallipoli was written by Swan and Doyle. This isn't an easy question and the common surnames of the authors aren't helpful either.
I think, but this idea is merely based on gut feeling, that the song is written in the anti-recruitment tradition during the First World War.
The use of the name Dún Laoghaire however is riddling. At the time of the First World War this port near Dublin was commonly known as Kingstown (a name granted in 1821 by King George IV to honour his own visit to Ireland).
In ancient times the village was already known as Fort (Dún) of King Laoghaire. Initially the Anglo-Saxons anglicised the name to Dunlary, or Dunleary.
Hence, is the song written between the Battle at Gallipoli in 1915 and the end of the First Word War in 1918 and used the authors the ancient - Irish - name or is the song written in the 1920's?
Thanks for thinking!
