Stars arrive for Band Aid 30 recording
Stars including Ed Sheeran and One Direction have been arriving in Notting Hill for the recording of the new Band Aid charity single.
Sam Smith, Elbow, Chris Martin and Bono will also sing on the reworked Do They Know It's Christmas?
Funds raised by the new recording will go towards the fight against Ebola and Bob Geldof told reporters outside the studio the UK government had agreed to waive VAT on the single.
