Email Template

Trying to figure out how to add the customers address to
the new payment email that the admin receives. Currently
they get:

New payment completed:
Product:
Amount:
Period:

User details:
Username:
Email:
Name:

--
Best Regards,


And I would like to add the physical mailing address to this email.
Which means adding the street, city, state, country and zip.

Can anyone point me in the right direction or a snippet of code.

I found the following in the /amember/common.inc.php

function mail_payment_admin($payment_id, $member_id){
global $db, $config;

$t = &new_smarty();
$p = $db->get_payment($payment_id);
$u = $db->get_user($p['member_id']);
$pr = $db->get_product($p['product_id']);
///////////////////////////////////
$t->assign('user', $u);
$t->assign('payment', $p);
$t->assign('product', $pr);
///////////////////////////////////
$et = & new aMemberEmailTemplate();
$et->name = "send_payment_admin";
mail_template_admin($t, $et);
}

But have no clue as to what code to add
