The epochal musical Hair is based predominantly on the actions and reactions to the cultural and societal occurrences of the Sixties. So, what can be done to help in the understanding of this historic musical? The answer: to produce an annotated text of the musical that will offer support to director and cast. The study consists of four chapters; the first, an introduction to the study; the second, a historical review (1960-1970); the third, the annotations which seeks to identify and explain all unfamiliar or unusual words, cultural obscurities, or personalities that might confuse, or otherwise mislead a full and comprehensive understanding of the author's original concept; and fourth, the worldwide performances of Hair and revivals after the original Broadway production.
