The rhythm of FE (→EE) is probably earlier or was even left inadvertently at the time of possible corrections in [A1]. Due to that, we give priority to the version of GE (also introduced into EE2). A similar difference also occurs in bar 71.
In both sources based directly on autographs – FE1 and GE – the slur in that bar continues the slur from bar 66. The remaining versions of slurring are, according to us, not authentic. An additional combination fully enables to independently treat the rhythm and slurring here.
