As the musical troop recorded the single, Chancellor of the Exchequer George Osbourne announced that the government would waive VAT for the single to ensure it raises the maximum amount of money to help combat the Ebola crisis.
"Just spoke to the remarkable Bob Geldof," tweeted the politician. "Told him we'll waive VAT on #BandAid30 so every penny goes to fight Ebola."
In a break from previous Band Aid records, some of the famous song's lyrics have been altered to link it to the Ebola crisis in Africa.
A new line reads: "Where a kiss of love can kill you - And there's death at every tear", while another adds: "Well tonight we're reaching out, and touching you."
"No peace and joy this Christmas in West Africa - the only hope they'll have is being alive," the song continues. "Where to comfort is to fear - Where to touch is to be scared. How can they know it's Christmas time at all."
Band Aid 30 will be released on Monday 17 Novemeber.
