When HAIR, The American Tribal Love-Rock Musical, opened on Broadway at the Biltmore theatre on April 29, 1968 the musical, with book and lyrics by Gerome Ragni and James Rado, music by Galt MacDermot and directed by Tom O'Horgan, broke new ground in musical theatre and the genre of the 'rock musical' was born.
