Tonight's 'We Are the World' update: Watch footage from inside the recording here!

The Haiti-benefiting 25th anniversary remake of "We Are the World" sung by half the music business on the day after this year's Grammys is set to premiere during tonight's Winter Olympics opening ceremonies, at 7:30 p.m. ET/PT (6:30 CT). MTV News has some preview footage from inside the recording session:

My favorite part of that clip is teensy little Justin Bieber intently reading a lyrics sheet as he sings the opening lines. (I'm not sure his parents were even born yet when the original version hit the airwaves waaaaay back in 1985, so I'll give him a pass on not knowing them by heart.)

Since I was on the scene for much of this momentous afternoon, I've already gotten more than my share of this updated tune — but what do you think of this snippet, Mixers? Do you like the polish RedOne gave the track? How do you feel about the fancy new syncopation on the chorus? Does Vince Vaughn = Dan Aykroyd? And do any of these soloists match the brilliance of Springsteen's "Weee are the wrrrrrrrrld" constipation, Cyndi Lauper's freaky "whoa-whoa-whoa-whoa"s or Huey Lewis's deeply inspirational take on "But if you just believe / there's no way we can fall?" (Short answer from this child of the '80s: impossible.)

Original after the jump, as a refresher. Meanwhile, who's got plans to tune in?
