CBS' 60 Minutes will devote its entire hour this Sunday to interviews with presidential hopefuls Barack Obama and John McCain.

In addition to the sit-downs, Variety reports, the coming installment will mark the news magazine's 40th anniversary. The original broadcast debuted on Sept. 24, 1968 with interviews of then-presidential nominees Richard Nixon and Hubert Humphrey. Obama will be interviewed by Steve Kroft, and McCain will chat with Scott Pelley.

Perhaps these interviews will refocus some attention on the candidates, who have taken a back seat recently to the media frenzy surrounding Republican VP hopeful Sarah Palin. She was recently interviewed by ABC News' Chales Gibson and Fox News' Sean Hannity, and she was hilariously lampooned by Tina Fey on Saturday Night Live. Her next stop is a chat with Katie Couric on the CBS Evening News.

Sunday's 60 Minutes will also mark the show's first high-definition broadcast. Will you be spending an hour with the candidates? And what will we possibly do without Andy Rooney's segment? - Adam Bryant
