Several songs deal with more serious and social issues; "No Son of Mine" tackles the subject of the domestic abuse of a 15-year-old boy which originated with Collins repeating the phrase "no son of mine" as a dummy lyric during the writing sessions, rather than a song concerning social commentary. "Dreaming While You Sleep" concerns a hit-and-run driver and his guilt after failing to stop at the scene of the accident. The former contains a sample of a sound that Rutherford achieved as he was "messing about bending two notes" that Banks had recorded from a microphone on his E-mu Emulator which he then sampled and slowed down, creating a noise he compared to an elephant's trumpeting. The ten-minute "Driving The Last Spike" is about 19th-century Irish navvies who helped built the railways in the UK, and the poor and unsafe working conditions they had to endure. Collins wrote it after being given a book on the subject by a correspondent who sought to produce a television show about it. Banks used a Hammond organ patch on the track, which referenced his prominent use of the instrument early in Genesis' career. The other long track, "Fading Lights", came out of group improvisation. "Since I Lost You" was written by Collins for his friend Eric Clapton. On 20 March 1991, Clapton's four-year-old son Conor died after falling from the 53rd-story window of his mother's friend's New York City apartment, landing on the roof of an adjacent four-story building. Banks and Rutherford were the only members in the studio that day, and played what music they had written to Collins the following day. Collins said, "Straight away, I was singing the things you hear on the record", and wrote a set of lyrics based on the incident, not revealing what they were about to his bandmates until he had finished them. Some lines were from a real-life conversation Collins had with Clapton following the incident. "Tell Me Why" criticises the Gulf War and the plight of the Kurdish people in its aftermath. Collins got the idea from a television news report while he was having dinner with his wife and daughter. "So I just mixed my feelings with previous thoughts about Bangladesh and Ethiopia".
