Cover art for There's Talk of Mine Shafts lyrics by Margot & the Nuclear So and So's

They put up their lyrics on their website now, and that last line is actually:

"And we'll escape BIBLICAL fate."

So I think that whole Romeo and Juliet, dying thing is actually a little off. The crazy verse at the end of "Mariel's Brazen Overture" I think, is signifying a war, and in the song I think its actually revealed to be some sort of apocalypse-event (biblical fate, what else could it mean?) so the two mice can live as the only inhabitants of a ruined earth together, as long as they hide out in the mine shafts.
