Preventing a post appearing in the menu

I’m trying to set up a site where the Home page gives general information while posts are displayed on a separate page that appears on the menu. The menu lists all pages, using the command:

<?php wp_list_pages(‘depth=1&title_li=’); ?>

I have set the Front Page Display to a static page called About, and the posts page to a blank page with the required title. However, what this means is that both Home and About in the menu, both directing the viewer to the same page. Does anyone know how I can exclude either the Home or About item from the menu so that I only have one menu item linking to this particular page?
