Stephen Stills' "Feed the People"

This morning I listened to Stephen Stills' Man Alive!, and I noticed a Biblical reference in "Feed the People."  There's the recurring line "Turn your swords to plowshares everywhere and feed the people."  Coincidentally, two days before I listened to the album, I read Isaiah 2, where Isaiah writes, "He [God] shall judge between the nations, and shall decide disputes for many peoples; and they shall beat their swords into plowshares, and their spears into pruning hooks; nation shall not lift up sword against nation, neither shall they learn war anymore" (Isaiah 2:4).  While Stills' song is primarily concerned with feeding people, through that Biblical reference, which - in its original context - is more about turning away from war, it also advocates pacifism.

Buffalo Springfield's "Special Care"

I just listened to Buffalo Springfield's Last Time Around for the first time.  At the very end of "Special Care," there are some spoken parts.  I can't make out all of them, but at the end there's "only some, they [are] more equal than others."

I'm not sure if it's intentional on Stephen Stills' part (although the similarities in phrasing suggest that it was a conscious quotation), but this is the same sentiment expressed in George Orwell's Animal Farm:  "All animals are equal, but some animals are more equal than others."

Buffalo Springfield's Buffalo Springfield Again

I just listened to Buffalo Springfield’s Buffalo Springfield Again.  What I found interesting was that on some of the tracks, the lead vocalist also sings the harmony parts.  Like on “Expecting to Fly,” Neil Young sings the lead vocal, and he also sings the harmony part.  See also “Broken Arrow” and Stephen Stills’ “Bluebird.”

Having both parts sung by the same person would give the song more coherence, but I’m not sure if that’s why they did it that way.  Judging by the Wikipedia page, it was more likely due to acrimony in the group or Neil Young’s frequent absences, but I’m hesitant to accept Wikipedia so readily and I’m not sure if those would explain all of the cases.  Incidentally, I have a book about Buffalo Springfield that I’d planned on starting soon.  Maybe I’ll find an answer in there.
