Actually, I haven't tried more than one \book{} in a .lytex file; I 
couldn't
get the first one to work.

The second line of the first page _is_ in the .eps file.  My guess is 
that
the "high above" text pushes it too low, and the second line gets cut
off by the bottom margin.

You didn't mention this, so I'm not certain if you see the same 
behavior:
On fink 2.5.23 (and your test file) my first page consists of only 
"Hello!";
there's a pagebreak, then the "high above" and one line of music on page
2.  It would great if this was tweakable; if breakbefore (or 
firstbreakbefore)
is false, don't insert a pagebreak before the \book.

OK, I understand that now.  I was previously thinking that the .eps 
wasn't
completely compiled; in other words,

{
  c4 c c c \break
  d^\markup{ \postscript #"foo" } d d d \break
  e e e e
}

would result in a .tex that looked something like this:
\include{picture1.eps}
\include{picture2.eps}
foo
\include{picture3.eps}
(and "foo" could be the TeX or postscript newpage command)

In other words, I guess I forgot that .eps stood for encapsulated 
_postscript_.  :)
Oh well.

If I can retain my LaTeX text at the beginning (and ending) of the 
pages, great.

In other words,

Page1:
LaTeX foo
+----+
|book |
+-----+


Page 2:
+-----+
|     |
|     |
|     |
+-----+


Page 3:
+-----+
|     |
+-----+
LaTeX foo
