apparently the inspiration for a tune and an album name - Deadly Buzz, Aoibhinn Crónán
I'm fond of Caoimhín Ó Raghallaigh's fiddling

I see now that Thomas the Rhymer does refer at the beginning of this discussion to Peadar O Riada's tune setting. I forgot!

"Aoibhínn Crónán - A Peadar Ó Riada composition to go with the words of a Douglas Hyde poem in Irish. Played as a slow air below, but could be played a bit more upbeat if required." The Session.
