"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.
"[4] The song itself shows Stevens switching from heavily orchestrated pop music to a folk-rock emphasis.
While recovering, Stevens donated his spare time, and some of his newer, more introspective songs for Colin Higgins and Hal Ashby's 1971 film soundtrack of Harold and Maude.
Most of the tunes used for the movie appear on Stevens's next albums, Mona Bone Jakon and Tea for the Tillerman, with the exception of two songs which were not released until the release of the album Footsteps in the Dark: Greatest Hits Vol.
