Also known as Southwind, The Southern Breeze, An Ghaoth Andheas, and so on. Has also attracted quite a few sets of words. Recently crossed my radar when working up some material with a ceilidh band, and I couldn’t resist trying it out. I may well vary the instrumentation for the ‘real’ version, but I quite like it with just guitar (though I’ve overdubbed here).
Sometimes attributed to O’Carolan, but I don’t believe there’s any proof of that, though Greg Clare tells me that it’s often performed along with Planxty Fanny Power (which I believe is O’Carolan) or Planxty Irwin (which is on my to-do list). The Fiddler’s Companion attributes it to Domnhall Meirgeach Mac Con Mara (Freckled Donal Macnamara) and includes Gaelic words and translation as well as much more information.
