During the summer of 2004, Kiss headlined the Rock the Nation 2004 World Tour, with Poison as the opening act. The tour ended in August with a sold-out show in Mexico City. Selected dates on the tour were filmed for the "Rock the Nation Live!" concert DVD, released on December 13, 2005. Stanley, who had been experiencing increasing difficulty with his hip, had his mobility limited during the tour. He has already had two hip surgeries performed, with more likely in the future.
