Random Posts (query_posts) doesn't display comments

I’ve created a custom template to display a random post page template for a particular category.

Here is my main loop:

<?php query_posts('showposts=1&cat=3&orderby=rand');?>
		<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
   <?php the_content(); ?>
        <?php comments_template( '', true ); ?>
		<?php endwhile; endif; ?>

But it doesn’t display the comment form.

When I include a reset query, it does include a comment form, but it is the comment for that particular post, not the comment form for the random post that is displayed.

How do I bring up the correct comment form with random posts?
