1. A number of songs (or song titles) either reference or use common sayings:
- "It may sound Greek to you" in "Weak for You" references "it's Greek to me"
- "See the forest for the trees" in "Weak for You"
- "Absence makes the heart grow fonder" in "Smooth Operation"
- The title "Shadow of a Doubt"
- "A month of Sundays" in "Shadow of a Doubt"
I don't really have anything to add to that; I just thought it interesting and wanted to note it.
2. The title Journey doesn't seem too far off from the title Odessey and Oracle, since journey is a synonym for odyssey, but I don't know if that's an intentional reference or just coincidence.
