NEW YORK - Imagine what might have happened to Katie Couric a couple of weeks ago if she hadn't kept her briefing books straight.
Tuesday, she interviewed Lil Wayne, bowling with him and inviting the rap superstar to watch from the control room as she anchored the "CBS Evening News."
Wednesday she talked to President Obama.
Thursday she reported news outside on a frigid night overlooking the Hudson River landing site of a damaged jet, and anchored a report on former President Bush's farewell to the nation.
Then she flew overnight to Los Angeles, where she spent time hanging out with Justin Timberlake, on Friday.
The collision between music and politics came because of a pre-Grammy Awards special Couric is hosting on Wednesday (9 p.m. ET). Besides Timberlake and Lil Wayne, featured artists are Katy Perry and Taylor Swift.
