I came on this tune in the "Thursday Sessions tune books" www.andyhornby.net/thursday.html it is written here in 2/4 and I never thought of it as a hornpipe and I tend to try and play it on the fiddle with a bit of a lilting bounce to it.
It is subtitled in this tune book as "Planxty Madam Maxwell"
One of my own favourites that I keep coming round to
This is the same tune called Planxty Miss Maxwell on the Absolutely Irish All-Star CD with Mick Moloney. Correct? Reminds me of George Brabazan. I guess both tunes are attributed to Carolan. Both tunes sound like they should be played when the King or Queen enters the room.
