A world of charity concerts
The success of Live Aid in 1985 spawned over 20 years of mammoth charity concerts, which were set up to raise awareness of a variety of world issues.
Millions of pounds have been raised by pop stars and organisers for issues such as famine and Aids awareness.
Climate change is the next issue to be tackled, with eight Live Earth concerts planned around the world for 7 July.
Here are some of the highlights of the huge charity gigs staged since 1985.
