The song Do They Know It’s Christmas? was written by Mdige Ure and Bob Geldof in 1984 in order to raise money for the 1983-1985 famine in Ethiopia. In order to raise a lot of media interest in the single, and the cause it supports, Ure and Geldof recruited several leading British and Irish musicians who were popular at the time and formed them under the name “Band Aid”.
The song is the standard inspirational anthem, with the main selling point being that each of the participating artists – all of them popular at the time – sing one line each, until it culminates into the outro “Feed The World, let them know it’s Christmas time again.” sung by everyone in unison.
The artists that participated in Band Aid include Wham!, U2, Bananarama, The Police, Spandau Ballet, Duran Duran, Kool & the Gang, Big Country, Culture Club, The Boomtown Rats, Genesis, Ultravox, David Bowie, Paul Young, and Paul McCartney, making up a veritable Who’s Who of the billboard top charts at the time. Do they know it’s Christmas was revived twice since then, featuring new sets of artists and a few returning ones, dubbed Band Aid II in 1989 and Band Aid 20 in 2004.
