4:10 PM: Was studying while listening to Bach. Thought I heard Cream Lemon??? Turns out the opening sequence of Black Cat Mansion PC-98 used the motif of Partita No. 2 in D minor, BWV 1004 V. Ciaccona. Pleasantly surprised. Didn't even try to look for the origin and here it is. When can I finally find the chant playing in the background while Naomi fantasized about doing this and that to the new transfer student and the piano piece that Chikane played on that fateful night?????
