After I figured out the specific notes in some of the melismas in "Say You Don't Mind," I also figured out the bass part for the first verse. I had to record this using the fake upright bass setting on my keyboard though because I don't have (and don't really know how to play) an upright bass. Because of that and because it's mostly fourths and fifths, it has a resemblance to donkey braying.
I might also try notating as much as I recorded (which is all I know) because I think it's entirely quarter notes and eighth notes.
