Apply Selected Class To One <li> When Another <li> Is Clicked On

I currently have a script that dynamically adds a css class called "on" to a menu item once it is selected, turning that link red to show that it's active. Here is the web page: [URL] As you can see, if you click on "Dimmer" or "Pol Pot's Birthday", or one of the three Patriotville scene links (1, 2, or 3), those links stay red. But what I need to happen is that when the user hovers over OR clicks on "1", "2", or "3", the word "Patriotville" also turns red along with those links. Here is the current code:

<script language="JavaScript" type="text/javascript">
/*<![CDATA[*/
var Lst;
function CngClass(obj){
if (Lst) Lst.className='';
obj.className='on';
Lst=obj;
[Code]...
