The next day, Harold walks into the library to woo Marian in earnest ("Marian the Librarian"). For a moment, she forgets her decorum and dances with Harold and the teenagers. Harold kisses her; when she tries to slap him, she accidentally hits Tommy instead. With Tommy's help, Harold signs up all the boys in town to be in his band, including Winthrop. Mrs. Paroo likes Harold and tries to find out why Marian is not interested. Marian describes her ideal man ("My White Knight"). She sets out to give Mayor Shinn evidence against Harold that she found in the "Indiana State Educational Journal", but they are interrupted by the arrival of the Wells Fargo wagon, which delivers the band instruments ("The Wells Fargo Wagon"). When Winthrop forgets to be shy and self-conscious because he is so happy about his new cornet, Marian begins to see Harold in a new light. She tears the incriminating page out of the Journal before giving the book to Mayor Shinn.
