John McCain, live from New York

<p>My friends, it's John McCain, live from New York, just three days before the election.</p><p>Aides to the Republican presidential candidate said Friday that McCain will make a detour from battleground states to appear on "Saturday Night Live," the late-night show that has been a must-watch for many during the political season.</p><p>Hosting the show tonight is actor Ben Affleck, a supporter of Democratic candidate Barack Obama. The musical guest is singer David Cook.</p><p>When McCain's running mate, Alaska Gov. Sarah Palin, appeared on the show Oct. 18, "Saturday Night Live" earned its best ratings in 14 years.</p><p>Former star and head writer Tina Fey, a Palin lookalike, has been at the center of the show's recent parodies of the campaign.</p><p>McCain last appeared on "Saturday Night Live" in May, after clinching the nomination and while the Democratic primary continued. The 72-year-old Arizona senator joked about his age, saying: "I ask you, what should we be looking for in our next president? Certainly, someone who is very, very, very old."</p>
