Adding to the list of big-name entertainers coming to perform at inauguration parties, the Human Rights Campaign has enlisted '80s songstress Cyndi Lauper to perform at the LGBT group's inaugural ball. The Out for Equality Inaugural Celebration will take place Jan. 21 at the Mayflower Hotel. Tony Award winner Audra McDonald, Tony nominee Will Swenson and the Gay Men's Chorus of Washington, D.C., will also perform. E! News personality and "Chelsea Lately" regular Ross Matthews has been tapped to emcee the event. Matthews got his political feet wet over the summer, being sent by E! News to cover the conventions in Tampa, Fla., and Charlotte, N.C. Tickets for the HRC party are available online.
