When Rubinstein recorded the Chopin Waltzes in 1963,he chose to play the waltzes that had not been published during Chopin's lifetime,as Chopin composed them rather than using the Fontana versions.In this recording of the Waltz in A flat Op. 69 No.1, there are noticeable differences between the orginal autograph and the Fontana version. I am placing Cortot's performance of the Fontana version on You Tube for comparison.
