Rowsome’s or Kerry Jig
Joe McKenna, The Irish Low Whistle, track 4, first tune, followed by The Ballintore Fancy.
The same set is called a set of single jigs on Leo Rowsome, The King of the Pipers, track 2, and this tune is called The Kerry Jig (http://www.irishtune.info/tune/3147/), but to my ear it’s played as a reel, and only the second tune is played as a slide.
The same set is called "The Ballintore Fancy" on The Bothy Band, Old Hag You Have Killed Me (LP: Polydor Super 2383 417), side 2, track 4. Paddy Keenan comes in with this after an introductory piece (Ng’s irishtune.info #3148) that sounds as if it were written as a counterpoint to this tune. Both parts are played single, instead of double first part, single second as played by Rowsome and the Bothies.
