As with "Christ, unser Herr, zum Jordan kam" (#35), there's an instance where a note is given an accidental (G# in the bass clef in the fourth measure), but the second instance of that note in that measure didn't sound right with the same accidental. Actually, I didn't notice until I did the digital notation that I'd played it as a natural. I kept what I had though. Initially, this was partially because I didn't want to have to re-learn and re-record the piece and partially because I think a G# just sounds wrong, but when I lookt at the piece again later, I realized that there's a succession of ascending half steps in that phrase (G# A, F# G, D# E, and A# B), and this seems to confirm that it should be a G natural.
