Everybody cheats at it. I still havn't heard anyone play that piece well.
Gilels, Arrau, Richter, just for starters.
I have read Brahms 2 and easy it is not. Technique for the Brahms Paganini and the musicianship for Mozart 491 are required, and more.
On the other hand, many a pianist plays this, which can't be said of other very challenging works, like Bartok 2.
I am a Hamelin fan, but it sounds to me he has an emotional block with the main literature of the instrument. I like his Kapustin much better than his Haydn, even though I like Haydn better than Kapustin.
