Live Aid and Band Aid were the brain-children of Sir Bob Geldof, erstwhile BoomTown Rats frontman.
After watching news coverage of the famine in Ethiopia narrated by the BBC's Michael Buerk in 1984 he was so moved that he determined to something about it.
In collaboration with a whole string of artists who he cajoled and bullied into taking part, the Band Aid project was born.
Midge Ure (of Ultravox) co-wrote the song "Do They Know it's Christmas" and the accompanying video (filmed during recording) is a testimony to the number of artists involved in the project.
It awoke the nation's guilt and shot to number one, staying there for five weeks and outselling previous record-holders Bing Crosby and Frankie Goes to Hollywood.
Millions were made to help the starving and much of this was directed into self-help programs that encouraged a permanent solution to the famines
Following the success of Band Aid the Live Aid project was launched.
This was a massive worldwide live music event that took place in 1985 and featured just about everybody who was anybody in the music business.
At one point there was even rumour of a Beatles reformation with Julian Lennon taking the place of John.
Using the latest satellite technology the event was staged simultaneously in London and Philadelphia and ?50 million was raised in pledges by the massive TV audience..
Bob Geldof was knighted for his work in 1986 (albeit after his absence from the honours list and the poor excuses given were widely proclaimed an insult and a deliberate snub).
