Watch One Direction & Sam Smith In Band Aid 30 Charity Video

Yesterday we told you about how just about every U.K. pop star was joining forces for Band Aid 30. Now, you can hear the re-recorded charity single, which will raise funds for the prevention and treatment of Ebola in West Africa.

Sir Bob Geldof introduced the song and accompanying music video during tonight's episode of The X-Factor in the U.K. As with the original 1984 version, the video starts off with horrifying images of suffering in Africa. Pop stars then file into Notting Hill's Sarn Studios to record the song, followed by a mass group singalong.

The lads from One Direction kick things off on the track, a remake of the original Band Aid 1984 single, "Do They Know It's Christmas?" But, instead of '80s icons such as Duran Duran, Sting, and Boy George, this time we get Ed Sheeran, Rita Ora, Seal, Ellie Goulding, Chris Martin, Sinead O'Connor, and Sam Smith (with only Bono reprising his role from the original).

Donations can be made via the Band Aid 30 website. Proceeds from song sales will also be used to fight the spread of Ebola. In the meantime, watch the video below and just try to not get misty-eyed.
