O'Riada's settings are called "Aifreann Ui Riada" and "Aifreann 2" (?). There is/was a Gael Linn recording of both but their site reports it as out of stock. You may be able to locate a copy.

I have seen printed versons of the first setting - I may even have one around here somewhere. We can dig up details if necessary.

Good luck

Regards
