"A Man for All Reasons"

When I listened to Nexus recently, I also noticed a small feature in "A Man for All Reasons."  In the line "All his life will be unknown" in the sort of counterpoint vocal part, the phrase "all his life" is sung to notes of all different pitches (A G E), lending some sense of this entirety.

"Thunder and Lightning"

I listened to Nexus a couple days ago and noticed some significance in the structure of "Thunder and Lightning."

Obviously, the chorus repeats, and this repetition emphasizes the "Again and again and again and again..." in the last line.  The polysyndeton there (the repeated "and") highlights this recurrence, too.
