ATTENTION ALL MORRISSEY OUTDOOR CONCERT TICKET HOLDERS!

Due to the forecast on Thursday evening, there has been a change in location for the Morrissey Concert originally scheduled to be outdoor on 2/5/2009.

The outdoor tickets are now void. This show has been moved into the lobby. To be permitted into the indoor concert, you must re-register for the Morrissey Indoor Concert tickets. You will find this event listed separately on our website at: www.1iota.com.

These tickets for the indoor-concert will be distributed on a first come, first serve basis. This is a much smaller venue, so your requests must be in as soon as possible to reclaim a spot in the audience for this event.

Also, please note that when we hold a concert indoors, the age limit is raised to 18+ at Jimmy Kimmel Live.

We apologize for any inconvenience.

Sincerely,
Your 1-iota Team
