The following assumes you are using the default Kubrick theme for 1.5.
Do you want this to happen to ALL pages, or just some?
If ALL
1. copy page.php (in your current theme's directory) to page.old.php
2. copy single.php to page.php (now you see why we made a backup)
3. Tada. If you want the sidebar back, you'll have to find the class="widecolumn" and replace it with class="narrowcolumn" and then put: <?php get_sidebar(); ?>
right above <?php get_footer(); ?>
If SOME
1. Do the same thing, but instead of overwriting page.php copy single.php to a new file: pagecomm.php
2. Edit pagecomm.php to include the appropriate Template Name hook (you might read the whole article while you're there)
3. Edit the Page in question and tell it to use the new Template you've just created by selecting the new Template from the "Page Template" dropdown (below the main textbox).
