It Happened In Brooklyn (1947) - (Movie Clip) Johann Sebastian Bach

De-mobbed Danny (Frank Sinatra) gets a lift from schoolteacher Anne (Kathryn Grayson), acting on orders from a street cop, then to her classroom for her first vocal, a lyric from the credited songwriters (presumably Sammy Cahn, maybe Jule Styne) to a famous Bach miniature composition, Invention No. 1, in It Happened In Brooklyn, 1947.
