"I tried your four-billed therapy, I tried to make amends!"
"BY THE GRACE OF GOD ABOVE, EVERYONE SURVIVED!"
In all seriousness, I think my favourite stems from "In the Presence of Enemies'" third movement. "Welcome, tired pilgrim, into the circle; we have been waiting..." I kid you not, the way James sings that line sends such shivers down my spine!
In terms of song titles, I like either "The Great Debate" (for a "The" as the centerpiece) or "In the Presence of Enemies" (for a "The" as an almost-silent article, unnoticed but perfecting the title). I think about this stuff too much.
