I've known most of the bass part for "How We Were Before" for a few years, but I discovered that I'd simplified the part during the bridge ("And as you've waited for me…"). I'd figured it out (correctly) two different times, but I forgot to record it and then forgot how to play it. So I figured out it again and finally did record it.
I wrote it down too. I've started a binder where I'm going to write down lyrics, chords, and some notation.
This is supposed to use twelve-string guitar, but I just used acoustic because it's easier to play.
