Band Aid is 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-poverty 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 four days later. The single surpassed the hopes of the producers to become the Christmas number one on that release. Two subsequent re-recordings of the song to raise further money for charity also topped the charts. The original was produced by Midge Ure. The 12" version was mixed by Trevor Horn. It was announced on 7 November 2014 that a new version of the song will be recorded by artists under the name of Band Aid 30.
