After a number of close calls with potential assassins, Lennon was instrumental in setting up a charitable response to the famine in Ethiopia in 1984. In 1985, he was granted an amnesty by the Prime Minister on his tax and drugs problems and moved back to England, initially to organise the Live Aid concert with Bob Geldof and Midge Ure, at which the Beatles famously reformed under the joke name Sergeant Pepper's Lonely Heart's Club Band. They went on to release a number of charity records before finally releasing new material in earnest.
