After an emotional year, DAVID ARQUETTE will be here to tell Ellen about how his life has changed, his new role on "Dancing with the Stars," and how being on the show is helping him stay sober. They've risked their lives to perform for the troops in some of the most dangerous places on earth, and they're here today! One of the Air Force bands from the Missouri Air National Guard, SIDEWINDER, had a huge hit on YouTube this summer and now they're making their television debut on our show.
