Hi all!

I'm frantically cranking out orchestrations and scores for "Robin Hood: The 
Legendary Musical Comedy", which opens this Friday.
<http://harthouse.ca/robin-hood-the-legendary-musical-comedy/>

p.s. This is *by far* the largest project I've ever Lily-pounded!

Anyway, it's hardly critical (especially at this point in the process), but 
I have a quick question. In the vocals block, I've got soloists (with no 
start delimiter) and chorus (with a standard bracket). I want to connect all 
of the vocals with a straight bar delimiter — no problem. However, if there 
is ONLY chorus in the system, I want the "all vocals" (straight bar) 
delimiter to vanish. How might I accomplish this?

Thanks,
Kieren.

Others might have understood this, but I haven't.  Any chance of a mocked up 
image of what you want?
