Descriptions in new product listings - main page

Trying to work out how to add descriptions to new product listings on the main page. Found plenty of great posts on this forum about this topic, but unfortunately the template I purchased has different code in it for the new products section so cannot figure out what to change.

Can any code experts assist?

  $title = sprintf(TABLE_HEADING_NEW_PRODUCTS, strftime('%B'));

	if (!defined('IS_ADMIN_FLAG')) {
	die('Illegal Access');
	}
	// display limits
	$display_limit = zen_get_products_new_timelimit();

  if ( (!isset($new_products_category_id)) || ($new_products_category_id == '0') ) {
    $new_products_query = "select p.products_id, p.products_image, p.products_tax_class_id, p.products_price, p.products_date_added
                           from " . TABLE_PRODUCTS . " p
                           where p.products_status = '1' " . $display_limit;
  } else {
    $new_products_query = "select distinct p.products_id, p.products_image, p.products_description, p.products_tax_class_id, p.products_date_added,
                                           p.products_price
                           from " . TABLE_PRODUCTS . " p
