The frontman's wife was experiencing a difficult pregnancy with daughter Anna-Marie, and problems continued after her birth. He was also attempting to write a movie with The Exorcist director William Friedkin, all while Genesis tried to create their ambitious 1974 double album.

Hackett tells Prog's Daryl Easlea: "Pete was going through his version of Hell and I was going through mine. My first marriage broke up and I had a son. There was a tremendous amount of guilt - I just wanted to get on with the music, but modern life just kept crashing in all the time."

Gabriel eventually asked for time off in order to work on the film, but the band refused. Hackett says: "Friedkin freaked when he heard he could be responsible for breaking up the band. Pete came back to it."
