also print parent link along with child links

Before I discovered this excellent piece of code from the Fauna template – I was creating a different template for each page so that I could display the links to the child pages as required.

I have a question – the code will identify the parent page and output links to that parents’ child pages. How can I also print the parent page link just above the child links?

Thanks

<?php
$currentpage = $post->ID;
$parent = 1;

while($parent) {
$subpages = $wpdb->get_row("SELECT ID, post_name, post_parent FROM $wpdb->posts WHERE ID = '$currentpage'");
$parent = $currentpage = $subpages->post_parent;
}
$parent_id = $subpages->ID;
$haschildren = $wpdb->get_results("SELECT * FROM $wpdb->posts WHERE post_parent = '$parent_id'");
$parent_title = $wpdb->get_var("SELECT post_title FROM $wpdb->posts WHERE ID = '$parent_id'");
?>

<?php rewind_posts(); ?>
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>

<?php endwhile; endif; ?>
<?php rewind_posts(); ?>

<?php if($haschildren) { ?>
<ul>
<?php wp_list_pages('title_li=&child_of='. $parent_id); ?>
</ul>
<?php } ?>
</div>
