I read the text before I listen, so I was a bit worried about those drums, but they most certainly work; It didn't seem repetitive at all.
I, unfortunately, am not completely familiar with the source, so I can't say anything about how well the add-ins worked. However, I still think this is worth a download, and becoming part of my ever-growing OCR library.
... I am a bit biased. I love FF. I love piano... Its a great mix! And I don't mean the FF/piano combo.
Great job, and I'm hoping to see some more from you!
