Change Lyrics fontsize globaly

[Andreas Stenberg]

Hi!

Is there a easy way to change the fontsize of lyrics globaly. I'm 
working on projects with several files which are included in the final 
master file/ document and fidling around with fontsize comads for every 
single lyrics in every single file is starting to get bothersome. I dont 
know enough of the internals and i haven't the time to figure out hove 
to do this my self as I, as parttime leader of a church choire in midst 
of a proces of providing  new translations of an extensiv text material, 
have dead lines every other week.
The Lyrics fontsize shuold have to be changed globaly that is in the 
\paper block  in the master file producing the final document. I would 
be thank full to get something I quickly can copypaste into the last 
batch as I have a deadline looming over my shoulder and breathing down 
my neck about to bite me werry soooooooon.

Yours Andreas Stenberg
