Band Aid was a British and Irish charity supergroup, founded in 1984 by Bob Geldof and Midge Ure in order to raise money for famine relief in Ethiopia by releasing the record "Do They Know It's Christmas?" for the Christmas market. 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.
