For anybody who's currently in the vicinity, the following lecture on Thurs 20 May in Edinburgh may be of interest.
Breandan Ó Buachalla, visiting professor of Irish studies at Cambridge U.; "Poetry, Politics and Ideology in Jacobite Ireland", the O'Donnell lecture at the U of Edinburgh, lecture theatre B, David Hume Tower, Thurs. 20 May at 5.15 pm (It won't clash with any music sessions as they're normally after 8 pm)
I won't be able to attend as I'm too far from Edinburgh for a day trip, but I daresay ó Buachalla has published something on the subject.

Has the DT version of Mo Ghile Mear been improved yet?
