Pola Rapaport created the 55-minute film that incorporates archival footage from numerous U.S. and international productions of Hair. The documentary includes interviews with authors James Rado and Gerome Ragni, composer Galt MacDermot and Broadway director Tom O'Horgan as well as Oscar winner Milos Forman, who directed the 1979 film adaptation of Hair. Additional highlights of "Let the Sunshine In" include James Rado rehearsing Hair with various companies, as well as interviews with original Hair cast members Keith Carradine, Ben Vereen and Melba Moore.

The film features television appearances by Hair creators Rado and Ragni, both of whom starred in the original Broadway company. Michael Butler, who produced Hair on Broadway, also speaks about the creation of the landmark musical. In addition to the 55-minute documentary, the DVD boasts an hour of additional bonus footage.

Hair was the premiere production of Public Theater in 1967 under the auspice of Joseph Papp. Following a limited engagement at the Public, Hair transferred Off-Broadway to the Cheetah club, featuring a new cast, a new director, a revised book and additional songs. The Broadway production, which starred Rado and Ragni as Claude and Berger, respectively, premiered April 29, 1968, at the Biltmore Theatre.

The recent Shakespeare in the Park production of Hair, under the direction of Diane Paulus, will transfer to Broadway in 2009.
