Another world-class production

The charity anthem “We Are the World” has been rerecorded by 80 artists who came together in the same Hollywood studio where the original was cut 25 years ago.

Pink, Natalie Cole, Kanye West, Jennifer Hudson, Snoop Dogg, LL Cool J, Celine Dion, Barbra Streisand, Wyclef Jean, Lil Wayne and Brian Wilson were among the stars on hand at Henson Recording studios Monday night to raise money for Haiti earthquake relief.

“This one, the enthusiasm, I’ve never seen anything like it,” said Lionel Richie, who wrote the original with Michael Jackson and oversaw the new version with music mogul Quincy Jones, who produced the 1985 anthem.

“We Are the World – 25 for Haiti” will premiere this month during coverage of the opening ceremony of the Winter Olympics on NBC.

The original version featured 45 superstars including Jackson, Richie, Stevie Wonder, Bruce Springsteen and Cyndi Lauper.

It raised more than $30 million for USA for Africa, a nonprofit organization founded to fund hunger relief in Africa.
