Please help me add comment count to plugin

Thank you for your help in advance — I would try to figure this out myself but it could take a day, or a week.. So I figure why not let the experts help.

I use a plugin – wp-catlist that shows all posts in a category…. and it produces the output on “https://www.samdiener.com/article-list/”

I would like to add the comment count to the plugin. So it produces:

Title Yadi Yadi Yada, (X comments)

The code in the plugin that produces the post title output is/are:

foreach($catposts as $single):
			$output .= '<li><a href="' . get_permalink($single->ID).'">' . $single->post_title . '</a>';
			if($atts['date']=='yes'){
				$output .=  ' - ' . get_the_time($atts['dateformat'], $single);//by Verex, great idea!
			}
			if($atts['author']=='yes'){
				$lcp_userdata =

I am assuming that it is get_comment_count($single) or something, but I don’t know enough wp/php to add it to the code without killing it completely. Whoa is me.

Thank you? and thoughts?
