lilypond-book problem

[Jamie Bullock]

Hi!

I have three lilypond scores in three separate files. I am trying to
make them into a book with the following lytex file:

        \begin {document}
        \lilypondfile {score-I.ly}
        \lilypondfile {score-II.ly}
        \lilypondfile {score-III.ly}
        \end {document}

I then use the following command:

        lilypond-book --output=mybook -f latex mybook.lytex

This runs smoothly and without error, however, when I run:

        latex mybook/mybook.tex

I get the following error:

        ! LaTeX Error: The font size command \normalsize is not defined:
               there is probably something wrong with the class file.

Any help would be appreciated.
