G'day,Sorcha,
I doubt that the Exile of Erin / Plains of Emu I raise in the 1999 thread could be the one that Jed Marum is after ... but I suspect our Irish convict in Australia had read that one and "parodied" its form.
I did see the earlier one in a thread (the 1999 one?) and the original has southern aspects, whereas the Australian one seems to have northern connections. ( ... Or was that the other way round ... ?)
Regards,
Bob Bolton
