Excerpts on page template

Have a problem populating a page of taxonomy posts, I wonder if someone can help.

Using this method to get the posts where $taxonomy == ‘localities’ works in terms of correct posts being returned however it wont return excerpts at all.
Not sure if its related or points to something I have done wrong in setting up the Taxonomy but using the tax_query method fail to find any posts!

$paged = true by the way, though have tried false as well in case I had misinterpreted.

Select all
    $args=array(
    //    'tax_query' => array(
    //        array('taxonomy' => $taxonomy,
    //            'field' => 'name',
    //            'terms' => $local_name,
    //        )
    //    ),
        'localities' => $local_name,
        'post_type'     =>    'post',
        'post_status' =>    'publish',
        'posts_per_page' => -1,
        'caller_get_posts'=> 1,
        'paged' => $paged,
    );

    $temp = $wp_query;
    //$wp_query = null;
    $wp_query = new WP_Query($args);

Any thoughts would be much appreciated.
Cheers,
