Harvey, I'm jealous that you went to a Billy Joel concert!  Billy's one
of the few pop stars whose popularity spans across generations.

Concerning the Kurzweil piano, when I was in San Diego last fall, there
was a piano store near the hotel where I stayed.  When I visited this
store, there was an advertising poster on the wall featuring Billy Joel
promoting Kurzweil pianos.  I was rather surprised because I'd never
seen him promote any product before.  (I'd love to have my own copy of
that poster!)

Because of this connection, it wouldn't surprise me a bit if Billy's
Kurzweil piano is custom-made.
