WASHINGTON, D.C. Tuesday Jan.11.2005 /netmusiccountdown.com/ -- JoJo and Hilary Duff will help celebrate President George W. Bush's inauguration by performing at a youth concert on January 18 in Washington, DC. The concert, called "AmericaRocks Today: A Call to Service," is being organized by the President's daughters, Barbara and Jenna Bush. Kid Rock is also on the show's lineup, which has some conservative groups in a rage due to Kid's less than politically correct antics and song lyrics. However, Kid has not yet confirmed his appearance at the concert.
