Overriding/adding specific fields to slideshow controls template

I've created a file view called "image_gallery" outputting these fields:

• filename
• field_taxonomy_publications
  • This field is a term reference, rendered in plain text and attached to my files via the File entity (fieldable files) module.
• field_body
  • This field is a textfield, rendered in plain text and attached to my files via the File entity (fieldable files) module.
• URI

I'm using the EVA: Entity Views Attachment module to attach this view to my "Gallery" nodes. Furthermore, i've created a relationship of "File: Content using [MY_IMAGE_FIELD]" and then, using that relationship, a contextual filter of "Content: Nid" (default value being "Content ID from URL"). This all means that the images my users add to their nodes with display as proper views slideshows.

I've created a template with the name "views-view-fields--image-gallery.tpl.php" to render the images with proper title and alt text. Here's the code:

<img
	src='<?php print image_style_url('MY_IMAGE_STYLE', $fields['uri']->content) ?>'
	alt='<?php if (!empty($fields['field_body'])) print $fields['field_body']->content ?>'
	title='<?php print $fields['filename']->content ?><?php if (!empty($fields['field_taxonomy_publications'])) print '&nbsp;&#124;&nbsp;' . $fields['field_taxonomy_publications']->content ?>'
/>

This is all working swimmingly.

I've also copied "views-slideshow-controls-text.tpl.php" from views_slideshow > theme to my themes template folder.

My goal is to print out two specific fields in-between the "previous" and the "next" controls. I want to print out the very same title string that can be seen in the above code, concatenating the "filename" field and the "field_taxonomy_publications" field. Also, i've eliminated the pause control, as it is unneeded. So the code would look something like this:

<div id="views_slideshow_controls_text_<?php print $variables['vss_id']; ?>" class="<?php print $classes; ?>">
  <?php print $rendered_control_previous; ?>

  <markup>"filename" field + " | " + "field_taxonomy_publications" field</markup>

  <?php print $rendered_control_next; ?>
</div>

I've toyed around long enough with "views_embed_view" and "views_get_view" without any success. I'm stuck.

Any help is greatly, greatly appreciated.
