"Do They Know It's Christmas?" gets fresh sound for Ebola crisis

In 1984, music stars gathered to record the charity single "Do They Know It's Christmas?" The group known as Band Aid brought in millions of dollars to fight famine in Ethiopia. Now a new generation is using its voices to combat the latest crisis in West Africa, reports CBS News correspondent Charlie D'Agata.

Band Aid is back with some fresh faces and a whole new cause.

One Direction, Ed Sheeran, Rita Ora are a few of the artists who make up Band Aid 30, though most of its new members haven't quite reached that landmark yet.

The tune remains the same, but the words have changed, to reflect Africa's current crisis: the Ebola epidemic.

Once again, it was musician Bob Geldof who inspired Britain's biggest stars to come together.

"The only similarity between '84 and now is that it is the poorest as ever who get attacked and that makes me enraged," he said.

Differences include voices like George Michael, Simon le Bon and Sting of the original recording who were not featured on the new track.

Another change was made to Bono's facetious phrase from the original song "Well tonight thank God it's them instead of you," has been changed to, "Well tonight we're reaching out and touching you."

Just like a generation before, the new stars packed into the studio for one marathon session until the song and video were done. They used the same studio, on the same street, where history was made thirty years ago.

Rock critic Andrew Mueller admitted Band Aid 30 may not live up to the original act.

"It's impossible to imagine anything having the cultural or fundraising impact of the first Band Aid, but it won't be the last charity record that we ever hear of -- and hopefully not," he said.

At the moment, the new group's main goal, and really only goal, is to sell a lot of singles, raise a lot of money to fight Ebola, and help save as many lives as they can.

As Sir Bob put it: "It really doesn't matter if you don't like this song, it really doesn't matter if you hate all the artists. What you have to do is buy this thing."
