so it was just some broken keys? that's pretty bad for a
concert pianist.... just like driving F1 race cars with flat tires?

I don't know why the original story of "piano destroyed"
made me think of a grand piano being pushed out a
747's cargo door and landing on the tarmac in pieces.

Many years, I saw Claudio Arrau's piano(fully crated in a metal
container) being loaded on a plane at Frankfurt. I didn't actually
see Arrau board the flight, but the FA said he was up in first
class. (I was in steerage)
