The classic "We Are The World" single is back. To mark the 25th anniversary of the song, Lionel Richie, who wrote the tune with Michael Jackson, headed up the new version with the track's original producer Quincy Jones on Monday night (February 1st) in Los Angeles.

"We Are The World -- 25 For Haiti" will premiere this month during the opening ceremony of the Winter Olympics on NBC. Proceeds from the single sales will go to the victims of the Haiti earthquake. In an effort to create a fresh version of the track, none of the artists from the 1985 single were at the sessions. But the recording did take place at the Hollywood studio where the original was laid down.

Janet Jackson was expected to lay down her version of Michael Jackson's part on Tuesday (February 2nd), and there's a chance that other artists could come through some time this week to pitch in.
Michael Jackson's previously recorded voice will be heard in the remake as well.
The original recording session, which took place on January 28, 1985, featured 46 pop and rock stars, including Diana Ross, Bruce Springsteen, Billy Joel, Ray Charles, Tina Turner, Stevie Wonder and Willie Nelson, among others.
There are rumors that some music artists declined to particpate because the original song had been altered.
