Band Aid 30 "Do They Know It's Christmas?" (Andy Morahan, dir.)

It's likely the all-star line-up that draws you to this remake of "Do They Know It's Christmas," but director Andy Morahan knows not to waste those opening few seconds on mere celebrity; Instead, we get a very direct look at the devastating effects of ebola.

After that we fall into the same model as the original Band Aid video, but with a new generation of stars: Ed Sheeran, Sam Smith, Rita Ora, One Direction, Ellie Goulding and Chris Martin — plus, of course, Bono and Bob Geldof from the original Band Aid, as well.
