For some reason I get an error message every time I try to post below Adam's question. Anybody else having the same problem? To answer Adam's question:

The Hovhaness is indeed written for Xylophone and Orchestra. The parts can be rented from Edition Peters in New York. I've never played this piece, so I can't really compare it to the Rosauro, but I'm looking at a copy I just pulled of the shelf and it looks like a high-speed 2 mallet affair. Let me know if you have any more questions.

Oh-oh!

I've hit the hard coded limit of 2000 message per board.
I have now increased it to somewhat an arbitrary number, so, hopefully, it would be all right.
I have not done the checking so, there might be some other places that I have to fix as well, but for the time being...
