Last attachment post duplicating

Trying to trouble shoot why the last attachment in our post is duplicating. Example post:
http://www.ourgoodfight.com/?p=6165

Here is the code that is generating the attachments

<?php
$args = array(
	'post_type' => 'attachment',
	'post_mime_type' => 'audio/mpeg',
	'numberposts' => -1,
	'orderby' => 'menu_order',
	'order'  => 'ASC',
	'post_status' => null,
	'post_parent' => $post->ID, // this post
	);
?>

<!--This is where the audio attachments will go -->

<?php $posts = get_posts($args);
foreach ($posts as $post) : start_wp(); ?>
<p>
<a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title_attribute(); ?>"><?php the_title(); ?></a>
</p>
<?php endforeach; ?>
                            <!--This is the end of the audio attachments -->

Thanks.
