The First and Second Ladies of the United States got an early start on the 2013 Inauguration celebrations at a concert honoring our military families. The Kids Inaugural Concert: Our Children, Our Future was hosted by Nick Cannon and featured artists including Katy Perry, Usher, the cast of “Glee,” Far East Movement and Mindless Behavior. JR Martinez, the Army hero who won “Dancing with the Stars,” also joined Mrs. Obama and Dr. Biden for the event, which was held at the Washington Convention Center.
