Following his conversion to Islam, Cat Stevens (now named Yusuf Islam), abandoned his musical career for nearly two decades. When he became a Muslim in 1977, the Imam at his mosque told him that it was fine to continue as a musician, as long as the songs were morally acceptable, but others were saying that "it was all prohibited", and he decided to avoid the question by ceasing to perform. [86] He has said that there was "a combination of reasons, really", and that the continuing demands of the music business had been "becoming a chore, and not an inspiration anymore".

The first was released by Polygram on its recently acquired Island Records label in January 1990. Its cover picture appears to be a reference to the Teaser and the Firecat album cover; both feature a boy in a top hat, "Teaser", accompanied by an orange cat, "Firecat", beside a fence with a full moon overhead.
