When I listened to Pool It! last week, I noticed an allusion in "Since You Went Away" (which I think I'd noticed before but forgotten about). I'm not exactly sure how to format it, but the line "Could be the eagle finally has landed" refers to the Apollo 11 moon landing. The lunar excursion module was named the Eagle, and Neil Armstrong radioed back to mission control that "The Eagle has landed."
When I transcribed a bit of the lyrics this morning in order to write this post, I realized something else: "since you went away" in the line "Things are much better since you went away" could be temporal or causal.
