For over 40 years HAIR has amazed, shocked and delighted millions of people in hundreds of productions around the world. Originally conceived by actors James Rado and Gerome Ragni, with music by Galt McDermott, HAIR brought the radical hippie counter-culture lifestyle that was synonymous with New York's East Village in the 1960s, to Broadway and the rest of the world. ''Hair: Let the Sun Shine In'' is the first and only authorized history of the musical, from its original conception, up to the 2009 sell-out Broadway production and the spring 2010 London revival, including such pivotal points as the real life events that inspired its creators, the original off-Broadway production, the 1968 move to Broadway and recent productions from around the world. The book will also look at the themes that run through HAIR to reveal why it continues to create so much controversy and shows how the show broke new ground in terms of musical theatre. Also featuring 200 photographs and a stunning removable poster, ''Hair: Let the Sun Shine In'' will tell the complete story of the musical that defined an era, and which today, according to ''Time'' magazine 'seems...more daring than ever.'
