Just to expand a bit on Simon's reply: anything inside brackets is taken 
as a music expression by LilyPond, while \fontsize needs to be placed in 
a non-musical container, such as a \markup. I see you are working 
through the Learning Manual, and you will find more help a bit further 
down in 3.4.4 and 4.7.2 of that manual. Simon has also recommended that 
you try posting to the user list first, for your next questions, keeping 
the bug list for those issues which cannot be answered elsewhere.

peace so much that one of these days governments had better get out of
