I remember a tour guide during my college commencement ceremony once said that if you dove into the Hudson or East rivers that you'd come out with another limb. But no one said anything about a grand piano.
A spectacle, certainly, everyone seems to be on the up about a concert grand piano that has washed up near the Brooklyn Bridge.
And as Norman calls it, in any other major city (i.e. anything European) the piano may have made for a nice restoration project for some museum.
