Neil Patrick Harris sat down with David Letterman on The Late Show on June 3 to talk about hosting the Tony Awards and to show Broadway fans what's in store for them. NPH told Letterman that he’s going to make the typically flamboyantly fabulous event even more flashy. As a new producer of the 67th annual Tony Awards, Harris said he put some of his own ideas into the script, because he "hated the idea of showing up and just reading a teleprompter." Watch the clip below to see the Emmy winner reveal a special, "secret" clip of his rehearsal for Sunday night's big opening number. The Tonys will air on CBS on June 9, live from New York City's Radio City Music Hall.
