Here's a tune from the playing of the late Mickey and Francie Byrne from Kilcar in Donegal. I think the name comes from the Irish "Ríl na nGlórtha" meaning "The Reel of the Voices", rather than from its own, undeniably splendid qualities.
It's great on the fiddle as the second part gives plenty of scope for growling - The Growly Reel. You can sort of hum while playing the flute to get a drone effect but that's really, or ought to be, a private activity.
(This is as close as I remember it, Brendan)
