Hi Phil,

With only a very quick scan of my library, I turned up about a dozen that 
have a bar for the vox — they're mostly musical theatre scores (e.g., Les 
Miz, Sweeney Todd, Light In The Piazza, etc.), though some are "traditional" 
scores.

Aah.  I don't do MT :-)

1. As both conductor and engraver, I find the "loose staves" quite a 
distraction; the barred group is superior to my eye (and, apparently, to the 
engravers of the scores mentioned above).
2. Notation evolves to better service the needs of performers — just because 
Gould says something, doesn't make it so.  ;)

============================================================
Agreed.  She's good guidance though.

If I had to do what you're trying to do, I think I'd simply make 2 staves of 
chorus: "chorus with solos" and "chorus no solos" and let lilypond lose the 
relevant one at the relevant time.
