I was just doing some research on Seán Ó Duibhir a' Ghleanna and came upon this fascinating and informative thread. I've nothing to add about the song or the man, but I noticed that Martin Ryan (Hi, Martin!), Annraoi, and Áine lamented not being able to find An tAmhrán Macarónach by Diarmaid Ó Muirithe. Just by chance I found a copy in the bookstore of Cultúrlann on Falls Rd. in Belfast about 10 months ago. I bought it not knowing it was a hard-to-find book. I have no idea if they have more, but just knowing that new copies are floating around here and there might be heartening.

Cheers,

David
