Band Aid was the collective name of a charity supergroup featuring mainly British and Irish musicians and recording artists. It was founded in 1984 by Bob Geldof and Midge Ure to raise money for anti-famine efforts in Ethiopia by releasing the song "Do They Know It's Christmas?" for the Christmas market that year. On 25 November 1984, the song was recorded at Sarm West Studios in Notting Hill, London, and was released in the UK on Monday 3 December. The single surpassed the hopes of the producers to become the Christmas number one on that release. Three re-recordings of the song to raise further money for charity also topped the charts, first the Band Aid II version in 1989 and the Band Aid 20 version in 2004 and finally the Band Aid 30 version in 2014. The original was produced by Ure. The 12" version was mixed by Trevor Horn.
