Is there a way that I could add the address as it currently appears in the footer widget to the footer itself, so it shows on the left hand side (and on 2 lines as now)?

There is no settings for that in the WordPress dashboard or Theme Options but you can add it somehwere above or below <?php sparkling_footer_links(); ?> in footer.php file.

I dare not mess around with that - far too complicated for me! Thanks very much anyway.
