Rock musical by GALT MACDERMOT, 1967 , with book and lyrics by Gerome Ragni and James Rado. Billed as "the American tribal love-rock musical," it was first performed off Broadway, then radically rewritten and presented on Broadway in 1968.

The play was shocking and scandalous for its time, because of the use of profanities, a brief scene (before the curtain falls on the first act) when the cast appeared nude, and its preaching of peace, love, and happiness.

Plotwise, Hair is a "nonbook musical," that is, it has no coherent storyline. But, lurking beneath the messages of peace and love is a strong commentary on the evils of the Vietnam War, capitalist society, and racism.

There are two categories of songs: those defiantly challenging of stereotypes (Sodomy, Colored Spade, White Boys/Black Boys, I'm Black/Ain't Got No), and those fusing rock with popular song (the title song, Aquarius, Frank Mills, Where Do I Go?, Easy to Be Hard, Good Morning Starshine, Let the Sunshine In).
