Want to add post tag name to body class - I am successful in using the code below to add category to body class -

 //adds new body class for post category
add_filter('body_class', 'add_category_class_single');
function add_category_class_single($classes){
     global $post;

    $category = get_the_category($post->ID);
    $slug = $category[0]->slug;
    $classes[] = 'post-category-' . $slug;

    return $classes;

however when i try to use get_the_tags i am not having any luck - any ideas?

That is because the get_the_tags() function returns an array with the tag id as the key value. You could use array_values( get_the_tags( $post->ID ) ). That should do the trick.
