I didn't know @Josephine and @Rubens were teacher/student, how cool!!
Rubens feel free to redistribute the notes between hands
This, IMO is the biggest challenge of Ffrench sheet music prepared by someone other than himself. One of the things, or maybe the biggest thing, that slowed me down with getting September Song into my fingers was trying to decide how I wanted to play the notes on the page, in particular the inner notes that could be taken by either the LH or the Rh.
Having played several other Ffrench pieces from official scores (i.e., scores that he released), I suspect the score for Sept Song would have looked very different if it was prepared by him.
I know it might sound weird to say that, but I know that there are lots of choices in notation, and I think most of the time, we don't see the alternatives and we just play what's on the page, so we don't even think about it.
