Midge Ure, one of the original forces behind Band Aid in 1984, is bringing together a new generation of artists 20 years on for a remake of Do They Know it's Christmas?
The singer recently returned to Ethiopia with Save the Children to see how the country had changed. The Government now runs early warning systems and distribution networks that were installed by the agencies to prevent famine. However, absolute poverty is on the increase.
"We are hoping the money raised will be used for developmental rather than sticking-plaster purposes," said Paul Hetherington, media officer for emergencies at Save the Children.
"If you look at all the big NGOs and how much their income has grown, there has been a huge change. Agencies have become an industry rather than just do-gooders. That is the legacy of Live Aid."
The Band Aid Charitable Trust, now 20 years old, has distributed more than £80m from royalties and donations since 1984 for emergency aid and development projects in Africa.
The initial single sold 3.5m copies in the UK alone, and led to the global fundraising effort Live Aid the following year.
