Latest Comments – how to add (excerpt)

Hello,
In my sidebar, I got a “latest commets” panel (www.ziemianiczyja.pl), which displays the author and the first words of a comment. I miss one thing: the title of the commented post.

The perfect line would be [who?] [comment’s excerpt] [original post title excerpt]

I don’t use any plug-in, it’s only this code:

<h2>Komentarze</h2>
<?php
global $wpdb;

$sql = “SELECT DISTINCT ID, post_title, post_password, comment_ID,
comment_post_ID, comment_author, comment_date_gmt, comment_approved,
comment_type,comment_author_url,
SUBSTRING(comment_content,1,30) AS com_excerpt
FROM $wpdb->comments
LEFT OUTER JOIN $wpdb->posts ON ($wpdb->comments.comment_post_ID =
$wpdb->posts.ID)
WHERE comment_approved = ‘1’ AND comment_type = ” AND
post_password = ”
ORDER BY comment_date_gmt DESC
LIMIT 6″;
$comments = $wpdb->get_results($sql);

$output = $pre_HTML;
$output .= “\n

“;
foreach ($comments as $comment) {

$output .= “\n

• “.strip_tags($comment->comment_author)
  .”: ” . “ID) .
  “#comment-” . $comment->comment_ID . “\” title=\”on ” .
  $comment->post_title . “\”>” . strip_tags($comment->com_excerpt)
  .”…

“;

}
$output .= “\n
“;
$output .= $post_HTML;

echo $output;?>
</div>

Maybe the option I’m asking about is already in the code, but simply disabled? (“\” title=\”on ” . $comment->post_title . “\”>” ???). I would appreciate any help.

Best,
Mariusz
