The 20th anniversary of the release of USA For Africa's charity single "We Are the World" will be celebrated Feb. 1 with the DVD "We Are the World: The Story Behind the Song." To be issued by Image Entertainment, the double-disc set culls together more than four hours of footage from the historic session, which featured some of the biggest names in music.

In addition to an expanded edition of the original "making of" special released on home video in 1985, "The Story Behind the Song" will include the 10th anniversary documentary about the song and two extra hours of rehearsal and recording footage.

Fans will also be able to utilize a newly created karaoke function to sing over the song's chorus and instrumental breaks. Additional clips include "We Are the World" performances at the Grammys, American Music Awards and Live Aid.

Bruce Springsteen, Michael Jackson, Ray Charles, Stevie Wonder, Bob Dylan and Diana Ross were among the artists on hand for the original Jan. 28, 1985, session that birthed "We are the World," which went on to sell more than seven million copies worldwide and win the song and record of the year Grammys.

The single and accompanying album have raised more than $60 million for African famine relief. Proceeds from the upcoming DVD will benefit the same cause.

"I wish I could say that 'We Are The World' solved all the problems it highlighted," says Ken Kragen, one of the original recording session's co-organizers. "Nevertheless, it did shed incredible light on those problems, galvanized many into action and set an example of what people can accomplish when they come together in pursuit of helping others in need."
