Sir John began his career on The Beatles' Apple label in the 1960s and was one of the few contemporary composers to find wide acclaim beyond the classical world.
He was nominated for the prestigious Mercury Prize twice - in 1992 and 1997 - and was knighted in 2000.
Despite being told by doctors that he would not be able to work after his 2007 heart attack, he did resume composing and premiered three works at the Manchester International Festival this summer.
