Some of these demos exist:

Walk on By with no vocals
A Tiny Fold with different approach
Down to Memphis, early draft (none of us but Emily have heard this one, ever... except maybe Matt)

there are plenty of others. I'm now going to hold out on asking nicely until post-album, because if any of them are going on the album in this form finally, I wouldn't want to be spoiled. It's looking like they may or may not be using the "Clementines" (in quotes because that was the era, not because of a song) era song versions of "Come Clean," (not Clementines at the time), "Last Chance America," and "Middle Management." Who knows.
