Martin says it with the music!!
I personally think this clip of Martin Donohoe at http://comhaltas.ie/music/detail/comhaltaslive_200_4_martin_donohoe/ eloquently addresses a couple of points that have been done to death in recent posts. His newly composed hornpipe shows that a modern tune can also be traditional while the title/dedication is to veteran Cork singer of "An Puc ar Buille" fame, Seán Ó Sé. I rest my case!
