The opening track, "Dance on a Volcano" was the first song written for the album. Rutherford felt in contrast to the material on "The Lamb...", it was easy to write, and was intended to show how Genesis would move forward. "Entangled" originated from a piece by Hackett that Banks particularly liked and went on to write the chorus and closing synthesiser solo. Hackett also wrote the lyrics which Collins thought had a Mary Poppins feel to them. Rutherford recalled that Hackett "started writing verses which were very airy-fairy and then he came down with a bang". "Squonk" is based on the North American tale of the Squonk which, when captured, dissolves in a pool of tears. The song combines a main theme written by Rutherford against a middle section written by Banks, and was designed to sound like Led Zeppelin's "Kashmir".
