"The Measure of Your Grace" is ever changing

This past Sunday I recorded more vocals, redoing the melody in places and adding a high harmony.  Then on Tuesday night I was playing it for my wife and decided to place the capo back one fret changing it from A# to A.  It was much easier to sing and eliminated the strain on the higher notes.  So, I may go back and record the whole thing a half step lower now.  It keeps getting better all around.  Hopefully, this makes the vocals more pleasing.
