Supress Instrument after P. 1

[Mark Mathias]

Partly to duplicate a 1910 popular song layout, and partly to continue growing in LilyPond skill, I'm wanting to suppress the bookTitleMarkup instrument field after page 1.     

I've read the sections on Titles and Headers, Customizing, etc., and other parts of the manual, and I've made a number of attempts, but I'm not yet at the point where I understand what to do.
