DRUMMOND CASTLE Melnet Tune of the Month 8/23

I haven't done ToTM for ages, but I was inspired by Becci's brilliant version. I figured out some chords this morning, and gave myself a challenge to complete the recording in the hour my wife's at the gym: so the final take from the hour will have to do. The ending is abrupt because improvisation went wrong and had to be trimmed.
The most enjoyable part was finding chords. This is what I came up with: in Am for DG fingering. (Though my CF box sounds in Gm on this recording)
Chords are thirdless, otherwise E & A are minor. Commas indicate barlines.
A_, C_, F_, G_,
A_, C_, FG, EA; Repeat
A_, D/B_, C_, G_,
AC, EF, FG, EA; Repeat
I have altered two or three notes of the tune in bar 2 and 3 of the B music. Otherwise it's the first tune in the collection in "The Session".
