I have listened to this album a lot, but has anyone noticed how the titles of other songs pop up in the lyrics of various songs! Am I correct and if so why?
Because Gabriel thought / thinks he's very clever! And not just the titles of songs either - in In the Cage, he sings "Raindrops Keep Falling on my Head" and "(My little) Runaway".
They're all listed in "The Annotated Lamb Lies Down On Broadway" by Scott McMahon et al.
