Video: Geldof: Hard To Get Acts Together One Direction's Niall Horan arrived to loud cheers from fans gathered outside a west London recording studio. He said: "To be involved and get invited by Sir Bob (Geldof) to do this is just insane, so it's a privilege to be here." Asked what he hoped to achieve, he added: "Hopefully it gets to number one and it raises a lot of money for a really worthy cause." Video: 1D's Niall Horan On Band Aid 30 Song organiser Bob Geldof revealed Chancellor George Osborne called him earlier to say the Government will waive VAT on the single, meaning all the money raised will go to charity. He said: "The next stage now is to turn this into a phenomenon like it was in the 80s, and the only way to do that is to get people to buy the thing." Geldof, who co-wrote the song with Midge Ure, also said he had been inspired to re-record the track because of the "phenomenal bravery of the NHS doctors and nurses who volunteered" to help the fight against the virus. Video: Sande: 'Band Aid Important Cause' Some of the 2014 lyrics have been changed from the 1984 version to reflect the Ebola crisis. The original words: "Where the only water flowing is the bitter sting of tears" have been replaced with "Where a kiss of love can kill you and there's death in every tear." And the words: "Well tonight thank God it's them instead of you" have been changed to: "Well tonight we're reaching out and touching you." Bono sang the original line and is believed to be singing the new words too. Video: Band Aid 30: Paloma Faith The 1984 lyrics: "And there's won't be snow in Africa this Christmas time. The greatest gift they'll get this year is life. Where nothing ever grows. No rain or rivers flow. Do they know it's Christmas time at all?" have been changed to the following: No peace and joy this Christmas in West Africa. The only hope they'll have is being alive. Where to comfort is to fear. Where to touch is to be scared. How can they know it's Christmas time at all. The original words: "Here's to you. Raise a glass for everyone. Here's to them underneath that burning sun. Do they know it's Christmas time at all?" have been altered to say: Gallery: Stars Arrive To Record Band Aid 30 Single An all-star line-up of artists are arriving in London to record the Band Aid 30 single.
