NBC Universal came out with this statement following Kanye's offscript remarks:
"Tonight's telecast was a live television event wrought with emotion, Kanye West departed from the scripted comments that were prepared for him, and his opinions in no way represent the views of the networks. It would be most unfortunate if the efforts of the artists who participated tonight and the generosity of millions of Americans who are helping those in need are overshadowed by one person's opinion."
The NBC spokeswoman said that Kanye's (final) comment would be cut from the West Coast feed (but not, thankfully, from YouTube.) The show was live on the East Coast with a several-second delay. Whoever had his finger on the button was supposed to keep his ears peeled in case someone uttered an obscenity, but did not realize Kanye had gone off-script until it was too late.
The thing that gets me is the look on Mike Meyer's face, and the way both he and Chris Tucker keep glancing uncertainly side-to-side...of course, they actually keep to the teleprompt.
