Here's a piping jig which is good on the flute. It's an especially good one for learning.
I have a Seán McGuire LP somewhere with this tune on it. He called it "2 1/2 New Pence".
References to the monetary system in Belfast in about 1972 mightn't have stood the test or time, or be too portable, but I'm just passing on what tiny bits of information I might have about the tunes. I'll maybe be a bit more taciturn as regards the late phenomenon who was Seán McGuire.
