Band Aid is a charity supergroup featuring mainly British and Irish musicians and recording artists. It was founded in 1984 by Bob Geldof and Midge Ure to raise money for anti-famine efforts in Ethiopia by releasing the song 'Do They Know It's Christmas?; for the Christmas market that year.
Live8 was a string of benefit concerts that took place on 2 July 2005, in the G8 states and in South Africa. They were timed to precede the G8 conference and summit held at the Gleneagles Hotel in Auchterarder, Scotland from 6-8 July 2005. Both events also coincided with the 20th anniversary of Live Aid. Robbie played We Will Rock You, All These Things That I've Done, Feel and Angels.
BandAid20 was the 2004 incarnation of the charity group Band Aid. The group, which included Robbie Williams, Daniel Bedingfield, Dido, Thom Yorke, Chris Martin, Bono, and Paul McCartney, re-recorded the 1984 song 'Do They Know It's Christmas?', written by Band Aid organisers Bob Geldof and Midge Ure. The song was recorded on 14 November 2004, to benefit Sudan's troubled Darfur region, and was released that same month. The single became the UK's biggest seller of 2004 as well as the Christmas number one.
