using bold or smallcaps in lyrics in lilypond-book

[Davide Benini]

Hello folks.
I mailed this a few hours ago but it apparently didn't get through.  
Hope it's not a double.
After your previous suggestions, I am experimenting the use of  
lilypond-book for the small fragments of music in my LaTeX PhD  
dissertation. Here is an example of what I am doing:

blah blah blah blah blah blah blah blah blah blah blah blah blah blah  
blah blah blah blah blah blah blah blah blah blah blah blah blah blah  
blah blah blah blah blah blah blah blah

\hspace{1em}

\begin[fragment, staffsize=16]{lilypond}
        \new RhythmicStaff {
                \time 12/8
        \partial 8
                d8 d4 d8 d4 d8 d4 d8 d8 d8 d8  d4 d8 d4 d8 d4
        }
	\addlyrics{ Some TIME She  USED to PUT me THROUGH the re SPON se sof  
the MASS }
\end{lilypond}

blah blah blah blah blah blah blah blah blah blah blah blah blah blah  
blah blah blah blah


There are a couple of things I would like to do.
1) changing the font of the lyrics and (possibly) use bold or  
smallcaps in some words.
In the previous example, I use capitalised words to indicate the  
stresses (it is an experimental transcription of poetry); I would  
like to use smallcaps or bold instead. Is it possible? I tried the  
latex commands, but they do  not work in the lilypond environment.
Alternatively; I'd be happy with setting the global font to smallcaps.
2) eliminating the staff, or making it invisible.
I was previously advised to use the \override parameter, but I don't  
know where (and how) to place it in this short musical fragment.
The manual did not help.
Thanks in advance,
Davide
