"Trouble" is a song written by the English singer-songwriter and musician, Cat Stevens, during a period from 1969 to 1970. Stevens was recovering during what amounted to nearly a year of convalescence, after being diagnosed with a collapsed lung and tuberculosis. He spent three months in , Midhurst, England, transferring afterward to another nine months of bedrest at home. Stevens, who was near death at the time he was admitted in the hospital, used the time he was recuperating for contemplation, and wrote dozens of songs, including "Trouble", many of which were recorded much later.
