The concert also will be streamed live in high definition flash video on the official Operation MySpace page starting the day of the show at 11 a.m. PT.

In addition to hosting the one-time event, MySpace announced its official support of the America Supports You program as one of its ways to honor the dedication of members of the U.S. Armed Forces. America Supports You is an ongoing, nationwide program organized by the Department of Defense to showcase Americans' support for the men and women of the Armed Forces and their families.
