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.
