Is it possible to display a field value as part of Views title?
Changing a View's title is a theming issue. Have a look at Views: how to programmatically change Views title?. The accepted answer is almost what you need. Add the function to your theme's template.php file (or your custom module if you don't have a custom theme yet).

The rest is simply coding. Store the field that you need as a variable $my_field and adapt the code from the referenced answer as follows:

function MY_THEME_views_pre_render(&amp;$view) {
  if ($view-&gt;name == 'YOUR_VIEW_NAME') {
    \\ Store your field: $my_field = ...
    $view-&gt;build_info['title'] = "YOUR TITLE" . $my_field;
  }
}


You can use the Devel module to inspect $view in order to easily find the correct code for $my_field.
