Wp-login

I am trying to edit the wp-login.php without editing the core file. I have succeed through my functions.php file. but what i am trying to do is add text to the wp-login.php file through my functions.php. But i want the text to appear in the <div id=”login”> but if i do this

function logo_text() {
echo ‘<div id=”login”>’;
echo ‘<h1> My Text Here </h1>’;
echo ‘</div>’;
}
add_action(‘login_head’, ‘logo_text’);

it obviously creates a new <div id=”login”>….how can i add to the existing <div id=”login”> Hopefully I have explained this well enough, and can this be done through a function? what am trying to do is i have removed the WordPress logo through css and now i am trying to add text to replace the logo.
