On April 28, 1968, the Broadway musical "Hair" officially opened at the Biltmore Theatre in New York City. The groundbreaking production, created by James Rado and Gerome Ragni (book and lyrics) and Galt MacDermot (music), was a revolutionary piece that reflected the countercultural movement of the 1960s.

"Hair" was a radical departure from traditional Broadway musicals, featuring a racially integrated cast, rock music, and controversial themes such as the Vietnam War, drug use, sexual liberation, and the hippie lifestyle. The show's most famous songs include "Aquarius," "Let the Sunshine In," and "Good Morning Starshine," which became anthems of the era.

The musical's plot revolved around a group of hippies living in New York City, and their struggles with the draft during the Vietnam War. The main character, Claude, must decide whether to resist the draft or succumb to the pressures of his parents and society.

"Hair" faced controversy due to its nudity, drug references, and anti-war stance, but it also gained a dedicated following. The show ran for 1,750 performances on Broadway and spawned numerous productions around the world. It was also adapted into a film by Milos Forman in 1979.

The musical's impact on popular culture and musical theater was significant, paving the way for more daring and socially conscious productions. "Hair" challenged societal norms, addressed the concerns of a generation, and left an indelible mark on the history of music and theater.
