It depends on what's meant by correct.
Is it what's supposed to be done given the knowledge we know have 
available? Sure thing! Is it what's being supported by the existing 
tools out there, not a chance.

Attendee and Organizer are currently defined as email addresses. Using a 
vcard as the attendee is still in development and to be discussed.

When X2V interprets the hCalendar, it uses the existing mailto format 
and extracts everything inside of attendee.

ATTENDEE:MAILTO:Valient Thorr at 8:00 pm w/ Fu Manchu Fu Manchu at 8:30 
pm w/ Valient Thorr\, Artimus Pyledriver

We can tidy that part up by moving the organizer and attendee to their 
most appropriate parts, like their website or failing that, their name

The trouble comes when the computer tries to work out what property to 
assigen those values to.

hCalendar Parsing hasn't been defined yet, so it's still in flux.
In this case you're wanting to join together the names of both bands and 
have them on the mailto field called attendee. There are many problems 
with this, so the best options are to either provide an actual email 
address, or a link to their webpage.

<div class="vevent">
	<h2 class="summary">March 6th, 2007 at <span class="fn org 
organizer">The Black Sheep</span></h2>
	<p class="adr"><span class="locality">Colorado Springs</span>, <span 
     <div class="description">
         <div class="band">
             <h3><a href="http://myspace.com/valientthorr" 
class="attendee">Valient Thorr</a> at
                 <abbr class="dtstart" 
title="2007-03-06T20:00:00-08:00">8:00 pm</abbr></h3>
             <p>w/ Fu Manchu</p>
         <div class="band">
             <h3><a href="http://myspace.com/fumanchu" 
class="attendee">Fu Manchu</a> at
				<abbr class="dtend" title="2007-03-06T21:30:00-08:00">8:30 
             <p>w/ Valient Thorr, Artimus Pyledriver</p>

The info extracted from this is

X-WR-CALNAME;CHARSET=utf-8:Untitled Document
DESCRIPTION;CHARSET=utf-8:Valient Thorr at 8:00 pm \n w/ Fu Manchu \n\n 
\n Fu Manchu at 8:30 pm \n w/ Valient Thorr, Artimus Pyledriver \n\n \n
SUMMARY;CHARSET=utf-8:March 6th\, 2007 at The Black Sheep

It's still going to be officially wrong, but it's the best you're likely 
to do for now.
