Changing title and stanza font

[Christoph Bartoschek]

Hi,

how can I change the title font?

I tried to use

\markup { \override #’(font-name . "MetaPro-Bold") {"Title} } 

but this does not work.

Additionally I would like to change the numbering of the stanzas to my 
preferred font. I am able to change the lyrics font but the numbers are still 
in the old font.

This is how I add my lyrics:

\addlyrics {\override Score . LyricText #'font-name = #"MetaPro-Normal" 
            \set stanza = "1. " 
            text text text text
            ...
           }

Altogether I would like to change all fonts used to the MetaPro family of 
fonts. What is the easiest way to achieve this?
