The group USA For Africa reissued the Grammy-winning single recorded by more than 40 superstars--among them Bruce Springsteen, Ray Charles, Diana Ross, Bob Dylan, Bette Midler, Willie Nelson, Michael Jackson and Stevie Wonder--on January 31, as part of a two-disc DVD set.

The original single and accompanying album have raised more than $60 million since their 1985 release to help combat hunger in Africa. Proceeds from the upcoming reissue will again be earmarked for famine relief, as well as for AIDS treatment and prevention, plus disaster recovery in areas of East Africa devastated by the recent tsunamis, organisers said.

The double-disc set features four hours of footage from the landmark We Are the World recording session, which began late on January 28, 1985, and lasted 12 hours.

Inspired in part by the success of Bob Geldof's Band Aid project, which produced the British charity single Do They Know It's Christmas in 1984, We Are the World was the brainchild of American singer-activist Harry Belafonte.

After seeing news footage of Ethiopian famine victims, Belafonte contacted leading entertainment manager Ken Kragen for help enlisting stars to record a song whose royalties would go exclusively to relieve Africa's food crisis. There were no artist or agent fees.
