In all the Beethoven literature, it's described as lost. There are lots of alterations, changes, revisions that no one has ever seen.

A lot of us weren't ready for it. I'm thankful that we have a guy like Joe that will come out and push us to do it, not just someone who tells us to do it and walks away. He pushes you to work, and that's what everybody needs.

It's so touching. It means he played it.

Maybe, ... I'll be back next year.

[In another spot, Beethoven puts in numbers to signify the fingering.] It's so touching, ... It means he played it.

This is an amazing find.
