The right ending of the tie sustaining a2 was arranged slightly too high in FE (→GE1). In GE2 (→GE3→GE4) the tie was given an already totally erroneous form of a phrase mark combining a2 in bar 54 with d3 in bar 55. In the main text we give the only undoubtedly authentic version with sustained a2. We give the same version, written with a 
repeated before a2 in bar 55 (earlier notation convention), as a separate variant, due to the not entirely determined sound of the penultimate chord in bar 55.
