I only realized relatively recently, but the composition of this song is actually pretty weird - it's mostly in 12/4 time signature, and the chords are pretty strange as well, because there are so many different major chords played in the chord progressions (classic Tony Banks style), implying that the key keeps changing back and forth throughout the verses and chorus. The fact there are so many different major chords played in succession is part of what makes it so recognizable as being written by Genesis.
