Although this has been done, many times, many ways ... here is one more ... on the Esztergom, with its big acoustics!
It took me an entire week to download the 70G sample-set, so I had lots of time to figure out what I wanted to do first with it. So this is my "Ta-da! It's installed!" statement.
I also use the Brison "piano" score which other posters have used; with a few tweaks for organ and simulated timpani.
