...In passing I also note the use of the C-clef, but in an unusual 
position that makes it the same as a conventional G-clef.

The unusual C-clef is actually the same effect as using \clef "treble_8" 
but with a different symbol. Middle C ends up on the third space.

For me, that "ladder" clef symbol instantly identifies the song as a 
TTBB men's chorus arrangement. I'm attaching a PNG with a more-typical 
example of what I'm used to. LilyPond's standard C-clef symbol is 
something I hadn't seen outside of the software until two days ago, when 
I found it in an early-1900s men's chorus songbook at a garage sale. 
(The book was something like this one:

Is there any way to get that ladder-style C-clef in LilyPond? Although I 
can live with treble_8, typical TTBB men's chorus audiences here would 
expect the ladder. I remember seeing a discussion for generating a very 
similar symbol, but the right side of the ladder had "flags" going out 
from the top and the bottom.
