"Heady Days - A Memoir of a 70s AdMan in T&T" is a memoir of advertising executive Patrick Johnstone of his career in advertising in Trinidad and Tobago, from his teenage years to the creation of Publicis Caribbean Limited.

Johnstone's account of the advertising agency scene in the late 1960s to early 2000s is told with deep insight and a lot of irreverent accounts of the people and situations that he encountered in his profession. Not sparing tongue-in-cheek commentary and peppered with local aphorisms and typical "Trini" idiom, this entertaining book is geared to amuse and inform not only the "Mad Men" of his generation, but people generally in touch with the Caribbean and its idiosyncrasies.
