Ok, thanks.

Ok, good to know about \applyContext.  After looking into it a bit, I'm not 
sure whether it will do what I need it to do, but that's fine since this is not 
essential.  It's just something that would be nice to have.  I can always just 
copy and paste the music and then add or remove the overrides that go in it 
(one version of the music for each of the two staff types).  

(I also should be able to write some code to automatically do the overrides in 
my custom staff context instead of having to enter them manually.  That would 
be the ideal solution, and a better place to put the effort.)

Thanks,
