A quick look through the Roud index for the 1st line of the John Reilly versions seems to indicate that it's the version collected by Robin Morton from Sarah Anne O'Neill on the records: Topic TSCD 654 Farewell My Own Dear Native Land or Topic 12TS 372 On the Shores of Lough Neagh. This is the only version starting One evening fair to take the air. Sadly I have neither recording.
