Hyperlinking custom field

Hi,

Ive specified a custom field in my post body here http://festivalnet.co.uk/teas-and-tarts/ called ‘Website’ the user enters their URL via a contact form on the upload listings page here http://festivalnet.co.uk/upload-a-listing/

this is how i call it into the body

<span class="about-us">Website</span> <br />
                        <?php echo get_post_meta($post->ID, 'website',true) ?><br /

Is there anyway i can make the URL a hyperlink when its displayed in the post body?

Many Thanks
Al
