In 1968, the novelist and screenwriter Hanif Kureishi was a thirteen-year-old student at an all-male comprehensive school on the border between London and Kent. It was here that he was told by his music teacher Mr Hogg that John Lennon and Paul McCartney did not write the Beatles’ songs. The whole set-up, apparently, was a con. All that wonderful music had to have been written by others, most likely the more cultured Brian Epstein and George Martin.
