 "It Could Work" (sung by Frederick, Igor, Inga and Blucher upon discovering Victor's notes) and "Hang Him Till His Dead" (replacing "The Law").The character of Mr Hiltop is cut during "The Brain", by which Frederick's demonstration is performed on one of the students named Bertram Batram.The production is also notably reworked for intimate venues such as the Garrick Theatre to work as a vaudeville piece, unlike the larger scaled Broadway production.
