Composed by piano player Brad Fremlin. The A Part is a bit dark, and leads well into the B Part. Love the B Part. This tune is easy enough on a C-whistle, octave jumping those low-A’s works.
X1 is some combination of Richard Wood’s and Fiddler 3’s settings.
Alycia Putnam has a few more variations (ornamentation) on her record as well.
It’s played rather quickly on all three of these recordings.
A few minor variations, mostly from the two previous recordings cited.
The pick-up note into the A Part could also be a low-C, try it out.
Perhaps to a lesser degree, "AD^C D2E" may work in the 2nd bar of the B Part, instead of "ADC D2E", or, the original "ADD D2E".
