Two sections that were brought into the sessions from the start were a simple guitar riff that Hackett had been playing that the band liked and wanted to develop further and became "I Know What I Like (In Your Wardrobe)", and three bits from Banks that he initially thought were for different songs but were instead used in the final arrangement of "Firth of Fifth". The third section developed early on became the opening of "The Battle of Epping Forest", and the band repeatedly performed these three pieces daily for a short while which Banks thought resulted in the latter song being too overworked. Despite the setbacks, biographer Robin Platts wrote: "There were enough magic moments and inspired jam sessions to produce such enduring compositions".
