In A one can see here crossings-out and corrections in both parts; however, we were able to decipher only some of the crossed-out versions. The 2nd beat of b. 68 could have featured e (with a 
) in the L.H. and c
1-g1 in the R.H. It must have been d-f
that was on the 3rd beat in the L.H., perhaps as a correction of the version with d only. In the R.H., the top voice was not being changed, whereas the bottom one contained c1-f1 (to which Chopin eventually returned) and then a sole c1 note. At the beginning of b. 69 one can see two crossed-out L.H. crotchets – G-d-g, which were probably written first, and G-g.
See also b. 70.
