On Monday, some of the biggest names in music — One Direction, Bono, Sam Smith and others — released a Christmas-themed song to raise money for a good cause.
Of course, that story, and even the song in question, should sound familiar: The new single is the 30th-anniversary edition of Band Aid's "Do They Know It's Christmas?" — the song that in 1984 raised millions to fight famine in Ethiopia and, this time around, will raise money to combat the scourge of Ebola.
Back when the original version of the song was released, TIME took a look at the original Band Aid project and found that its impact reached far beyond one Christmas song, and even beyond the famine. The song "brought everything to a boil" and led to a trend in activist music that reached from Live Aid to FarmAid and from Artists United Against Apartheid to fashion designers raising money for food. The reasons for the trend, some suggested, ran deep:
Joan Baez, who agrees that this all represents "some kind of phenomenon," also suggests, "Rock 'n' rollers are answering a need of young people to make something out of ashes and silence. They have no leadership, no hero. They've been left nothing. But it's not just the kids. People in my generation or a little younger are longing for something they tasted and that went away." Comments Van Zandt: "The trend of activism is a natural thing after ten to 15 years of being in a coma."
