Boy band One Direction and U2 lead singer Bono joined some of the biggest names in British pop and rock music on Saturday to record a new version of the Band Aid charity song to raise money to combat Ebola in Africa. The single, "Do They Know It's Christmas?", was first recorded 30 years ago after musician and philanthropist Bob Geldof inspired a host of stars to come together under the Band Aid name to help those affected by famine in Ethiopia.
