Barbra Streisand was a surprise guest at Sunday's night's Emmy Awards, after some reports had said that she was going to be a no-show due to throat problems. But show she did -- not to pick up the Emmy she won for her "Timeless" TV special (her award was for individual performance and was her fourth Emmy) -- but to perform the show's finale. The star, 59, wearing a clinging stretch black dress she designed herself ("It's elastic, and it stretches -- and no undergarments") sang a heartstring-tugging rendition of Rodgers and Hammerstein's "You'll Never Walk Alone" on a set that was a memorial to the Sept. 11 victims. Speaking backstage after the show, Streisand acknowledged that this was her first performance of a patriotic (or any) nature since Sept. 11 and said, "I wasn't part of the other tribute that Hollywood did. I wasn't asked. I felt that I should make my presence felt in terms of my sense of patriotism and my love of my country. It was the right choice. We are all a bit frightened by the devastation that we experienced and the idea of biological warfare. It is like something out of the movies, only it is real. It is always difficult for me to sing. There is a sense of purpose now actually."
