Moments ago this was reported tonight in a Fanblast chat by Brett:

David will be singing and speaking  to a crowd of around 20,000 people @ the E-Center in Salt Lake City, Utah this Friday June 6th at 7:00 PM.

As a special thank you from David and the Archuleta’s, tickets are just $1.00 and go toward a charitable donation.

The news comes before it was released to the general public. More details will hopefully be announced soon and Fanblast will cover the event.
