squeezing a score onto fewer pages

[jeff covey]

apologies in advance for a simple question.  :)

i'm getting around to playing with one of my scores again.  this is
the first time i've tried producing a score and parts:

http://jeffcovey.net/music/scores/gershwin/rialto_ripples/

the score and the third guitar part look great, but the first and
second guitar parts each have one line by itself on a third page.
obviously, i'd like to squeeze each of them onto two pages instead.
i've played with the suggestions at:

http://www.lilypond.org/stable/Documentation/user/out-www/lilypond/Vertical-spacing.html

, but haven't found an answer.  what's the best thing to add to the
\score blocks in rialto_ripples-guitar1.ly and rialto_ripples-guitar2.ly?

thanks,
