"How to Succeed in Business Without Really Trying" is the Zeitgeist for the early 1960s. All of the numbers in the film version are superb, but here is our favorite (close second: "Gotta Stop That Man"). Robert Morse is brilliant here, and his role as a partner in Don Draper's ad agency in AMC's "Mad Men" was inspired casting. Like bookends for a commentary of those times. Enjoy.
