question on removing bar numbers

[Patrick Stanistreet]

I am including some inline code which is an attempt on my part
to print a drum score crib sheet without bar numbers. Commented out 
stuff doesn't work.

Bug?
The line #(set-default-paper-size "letter") seems to cause a
layout problem although my usage of it may be incorrect.

I noticed while adding the fourth line on the page that
the page layout would change dramatically.  Then after modifying
the header and just having only a title it seems that the layout goes
back to normal.  Until the 4th line on the page is added with
a title and a subtitle in the header the layout is normal
Of course commenting out the first line helps.


#(set-default-paper-size "letter")
\header
{
title =           "Lilypond drum pitches"
%subtitle =        "  "
}
