"How to Succeed in Business Without Really Trying is a 1961 musical by Frank Loesser and book by Abe Burrows, Jack Weinstock, and Willie Gilbert, based on Shepherd Mead's 1952 book of the same name. The story concerns young, ambitious J. Pierrepont Finch, who, with the help of the book How to Succeed in Business Without Really Trying, rises from window washer to chairman of the board of the World Wide Wicket Company." (Wikipedia)
Not finding good versions on YouTube (there are a few but they're really poor quality). There is a film version which is apparently light on music but a faithful adaption of the story.
