[SOLVED] Google Fonts for Rok Sprocket titles

I am searching for a way to add the link which is loading Google Fonts to the template Interior.
The reason is that I will use a Google Font for the titles of the Rok Sprocket slider.
Normally I add the link to index.php of the template, but that is not possible in this template.

In what file can I lace the link to the Google Font, so I can tell css to use that font for the titles of Rock Sprocket?

Hi there,
please take the file:
layouts/theme.php

Thanks for tghe quick reply.
It is solved.

Problem solved.
