Single.php in a Popup

Hi everybody!!

I’m doing a single page site (Argh!). Until now I was able to do everything, but I would like to open the individual post in a popup overlay on the page.
I added this code to call up the single.php inside the popup:

<?php include (TEMPLATEPATH . '/single.php'); ?>

but when it opens, it loads the entire loop of articles ??
Can be because it is inside the loop in the index?
Someone can help me?

This is the code of the entire loop:

<div class="newsBox1" id="container">
			 <?php query_posts(array('category__and' => array(1))); if (have_posts()) : while (have_posts()) : the_post(); ?>
                  <div class="box col1">
                        <p class="newsData"><?php the_time('j F Y') ?></p>
                        <h3 class="newsTitle"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>
                        <br />
                        <?php if ( has_post_thumbnail()) : ?>
                           <a href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>" >
                           <?php the_post_thumbnail(); ?>
                           </a>
                        <?php endif; ?>
                        <p class="news"><?php the_excerpt(); ?></p>
                        <div class="btnLeft"><a href="#" class="toPopup">Vedi tutto</a></div>
                        <div class="ffix"></div>
                   </div>
            <?php endwhile; ?>
            <?php endif; ?>
        </div>

<!--POP UP-->
<div id="toPopup">
	<div class="close"></div>
    	<span class="ecs_tooltip">Chiudi <span class="arrow"></span></span>
		<div id="popup_content">
			<?php include (TEMPLATEPATH . '/single.php'); ?>
        </div>
</div>
<!--POP UP END-->

Thank you all for the support!
Lot of love.
