I played this piece in a music festival in about 1977, and the day before yesterday I bought the Peters Urtext (of the whole suite - I also had an edition of the whole suite 42 years ago).
I was shocked to find that (memory issues aside) the version I played 43 years ago was probably simplified. I wonder which edition it was.
Afaicr, it was in A minor, whereas the Peters is in F# minor, but one's memory can play tricks with the key sig. The version I played probably wasn't 8 pages, but the real clincher is that I remember a fortissimo octaves bridge before repeating the main theme, which isn't in the Peters edition.
