The best examples, IMHO, of lyrics invading one's mind, is when by whatever reason a familiar Dead song throws up a few lines that you interpret anew. For me, this is most typical with Garcia/Hunter material. It usually happens based on a new life experience, but it can also happen out of nowhere by a surprisingly fresh interpretation.
To wit: despite Jerry shelving it after 3 live plays, I consider If I Had The World To Give top notch Garcia/Hunter stuff. And I digress by noting DSO seems to agree, as it pops up more than occasionally in elective shows. More digression: this shit fascinates me - what made Jerry take up great songs that he poingently delivered only to abandon them? Sing Me Back Home and She Belongs To Me are a couple other good examples.
World To Give is classic Hunter, whereby its thrust is powerfully uplifting, only to go against that grain while not in obvious fashion (and of course we all know Hunter thrived on the non-obvious nebulous verse).
Anyway, I'm trying to get to lines I heard in a newfound darkness. "Only if you let me be your world, could I ever give this world to you." What an awful concept, and what an unhealthy sentiment.
