Well, I didn't chicken out so I stopped by and asked about playing the piano at the hospital.
No dice unless you're a hospital employee. They told me the piano used to play by itself (pianoteq I assume because it's a newer piano) but that failed during a power outage 6 or 7 years ago and no one has played it since. I suspect it's not been tuned in that time either.
The hunt for a public piano to play continues!
Oh, and I have a better recording of Balestrand that shaves 15 seconds off the time from the last one. Still some issues, but I'll get there.
