Hair focuses on a group of hippies — called The Tribe — in New York City in the late 1960's, and gives voice to their passions and frustrations in loose scenes and interactions, including a rant against war, an embrace of free love (including a group nude scene) and odes to nature, life, drugs and multiculturalism. Book and lyrics are by Gerome Ragni & James Rado, music is by Galt MacDermot. Tom O'Horgan was the original director. Heather MacRae, Melba Moore, Keith Carradine and Joe Morton were among performers in the early Broadway run of the show, at the Biltmore Theatre.
