Sir Paul McCartney "forgets" to write "In My Life" – that was really John Lennon, said Harvard

I was a long and winding road, but academics may have finally solved the dispute over who wrote the melody of the Beatles song "In My Life".

The track has always been awarded John Lennon on the Beatles' album Rubber Soul album cover notes in 1965

Yet Sir Paul McCartney has long claimed that he had actually written the melody, telling Paul Gambaccini, the musician and commentator of the 1970s: wrote, and I wrote the piece.

American and Canadian researchers have concluded that Sir Paul is probably wrong because the song carries all the musical characteristics of Lennon

Mark Glickman, senior lecturer in statistics at Harvard University, and Jason Brown , professor of mathematics at Dalhousie University, created a computer model that broke down Lennon and McCartney's songs into 149 different components to determine the musical footprints of each composer
