Once I had a recording on tape taken from the radio back in the 1980th which I no longer possess. I remember the ‘Quiet Lands of Erin’ sung very freely. I have found a notation in a collection by Jake Walton which juggles enormously with the measure. So I tried to make a simple ABC from things at hand.
The key signature in the sheet music is shown as just a C flat, it should be a B flat
That’s just really an issue of resolution rather than an innacuracy in the ABCs. The flat symbols on the rendered sheetmusic are not very good.
