Adding category to List Category Posts using template

Hi there

I am using the List Category Posts plug in and have configured my own template as follows:

<?php
$lcp_display_output = '';
$lcp_display_output .= '<ul class="lcpgear_catlist">';
foreach ($this->catlist->get_categories_posts() as $single):
$lcp_display_output .= '<li class="lcp_li">';
$lcp_display_output .= $this->get_thumbnail($single, 'class', 'lcpgear_thumb');
$lcp_display_output .= ' ' . $this->get_date($single, 'class', 'lcpgear_date');
$lcp_display_output .= '';
$lcp_display_output .= $this->get_post_title($single, 'class', 'lcpgear_title');
$lcp_display_output .= $this->get_comments($single);
$lcp_display_output .= $this->get_excerpt($single, 'p', 'lcpgear_excerpt');
$lcp_display_output .= $this->get_content($single, 'p', 'lcpgear_content');
$lcp_display_output .= '<a>ID).'">Read more</a>';
$lcp_display_output .= '';
endforeach;
$lcp_display_output .= '';
$this->lcp_output = $lcp_display_output;

All is fine but I want to add the category itself with a link to other posts in the category in the normal way.

Although I can see that you add catlink=yes into the short code, I cannot get anything to work by adding a corresponding line of coding to the template. I assumed that this would do it:
$lcp_display_output .= $this->get_category$single);
but it just breaks the page.

Can anyone tell me the correct line of coding to add to the template to get the category/link to appear?

many thanks
