Release: "Do They Know It's Christmas?" was recorded in November 1984 and released in the UK in December of the same year. It became an instant hit, topping the charts and selling millions of copies. The song's success also inspired the later creation of "We Are the World" in the United States.

Lyrics: The song's lyrics express the urgency of helping those suffering in Ethiopia during the Christmas season and the hope for a brighter future. The lyrics include the famous line, "Feed the world, let them know it's Christmastime," which became an anthem for the charity cause.

Charitable Impact: The success of "Do They Know It's Christmas?" led to the Band Aid Trust, which raised substantial funds for famine relief. The song has been re-recorded multiple times with different lineups, including "Band Aid II" in 1989, "Band Aid 20" in 2004, and "Band Aid 30" in 2014, each time raising funds for various charitable causes.
