Ive been listening to a few pianists play this, and there are some different endings...for instance Horowitz one. (I think he adds this on on his own) http://www.youtube.com/watch?v=K78vuNYXzS4 Listen from 1:17-1:22, in the score its just a chromatic scale all the way up. but he seems to play a few notes, come down a few, and keep going up. If that makes sense and now I found two pianists that play a totally different and more exciting ending http://www.youtube.com/watch?v=Na1Qo06Sb5I listen from 1:15 to 1:24. Its very different than what the original score has... http://www.youtube.com/watch?v=HmkjEt2jWDk listen from 1:06 to 1:12 same thing as the previous one. http://www.youtube.com/watch?v=-Y0f8NeX ... re=related this one plays faithfully to the score. Does anyone know which version they are using ( the two pianists) ? And if they do, where can I get the sheet music?
