Il musical "Hair" ("Capelli") del 1969, diventato poi il film omonimo di Milos Forman del 1979, quando la fase hippy era ormai abbondantemente finita (praticamente già una operazione nostalgia).

Hair: The American Tribal Love-Rock Musical is a rock musical with a book and lyrics by James Rado and Gerome Ragni and music by Galt MacDermot. A product of the hippie counter-culture and sexual revolution of the 1960s, several of its songs became anthems of the anti-Vietnam War peace movement. The musical's profanity, its depiction of the use of illegal drugs, its treatment of sexuality, its irreverence for the American flag, and its nude scene caused much comment and controversy.
