Thanks, David....that worked! It left me with another problem to solve. . . I need that first page (now page 4 in our example) to act as an odd-numbered page, and I need the header not to print on the first page (page 4).
I have the following markup for the headers:
evenHeaderMarkup=\markup \fill-line { \fromproperty #'page:page-number-string \htitle \hcomposer }
oddHeaderMarkup=\markup \fill-line { \on-the-fly #not-first-page \hcomposer \on-the-fly #not-first-page \htitle \on-the-fly #not-first-page \fromproperty #'page:page-number-string }
