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... (more) 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. The group, comprised of servicemen and women, will perform Adele's hit, "Rolling in the Deep." Ellen surprised TAYLOR SWIFT at her concert in L.A. over the summer, and now Ellen is going to show an exclusive behind-the-scenes look at her Speak Now Tour. Taylor is here to discuss her steamy relationship rumors and to perform her and Ellen's song, "The Story of Us."
