Just listened to the demos:
Most of them are final versions, just like the demos from American Idiot. Exception is Misery, which has different lyrics on verses, almost like placeholders for a final song.
The demos sound more 90's Green Day, louder guitars and slightly fast tempos.
Waiting otis mix is awesome and I wonder if all those guitars were recorded back then and discarded on the final mix
Macy's Day Parade Otis Mix is like the acoustic songs from Saviors deluxe, they only removed bass and drums from the track
Maria is the single version
