Yes I know this is TAB talk, but you can't have a tab for a piano piece don't you?

Anyways, the guitar pro versions found in this site are incomplete and inaccurate (judging by the actual classical piece) and I can't find free sheet music that also is accurate (like in the first part of the song, the music sheets only show chords, and not the actual melody and such) in google and such.
And the threads in here are about tabs, but not about sheet music...

Can anybody help?
