This is another take on this melody. Both of these ring as Phrygian to me, with this take on the melody, "James O’Byrne’s" resolving on ‘B’ and thus being in the key of B Phrygian… Hey, there’s not a lot of these about…
Phrygeration ~
Sorry, I meant ‘A’ and A Phrygian… "The Castlebar Races" & "The Flying Dutchman" resolve on ‘B’ and are in my hearing B Phrygian… "James O’Byrne’s" given here with one flat is A Phrygian…
