Does anyone have piano sheet music to this track? If you could provide me with this I would be so thankful!

Considering it's just a remix of Uematsu's Crystal Tower from FFIII (fittingly), I don't see why it shouldn't be too hard to find, given the sheet music of the earlier FF games was released commercially. There was a thread in the downloads section that dealt specifically with sheet music so it might be worth a look there. :)
