As Band Aid marks 40th anniversary critics take aim at Africa stereotypes

Latest version of Do They Know It's Christmas fundraiser reignites debate about problematic' lyrics and imagery

Forty years ago this week, a group of pop stars gathered at a west London studio to record a single that would raise millions, inspire further starry projects, and ultimately change charity fundraising in the UK.

Do They Know It's Christmas, Bob Geldof and Midge Ure's festive charity behemoth, would go on to raise almost 150m for famine relief and development in Ethiopia and elsewhere in Africa. To mark the anniversary, on Monday a new version of the single - its fifth - will be released under the name Band Aid 40.
