Contrary to its lyrics of utter despondency wishing to block out the world, "World Without Love" featured the melodic, upbeat harmony pop-rock typical of the British Invasion, though an organ took the solo instead of a guitar. This was the most popular song written by John Lennon and Paul McCartney not to have been recorded by the Beatles, topping the U.S. singles chart in 1964. "The funny first line always used to please John," joked McCartney. "'Please lock me away ...' 'Yes, okay.' End of song."
