Yes, HAIR came out in the late 70's. But please don't call it a "disco-era" musical; there isn't a single thing in it that would suggest any detraction from its 1968 period. Judge it on its own merit; too often, a movie is compared to its stage roots and is inevitably crucified. As it is, the film plays out like one long, fantasy trip (whether that trip is substance-enhanced or not is your call)- starting with the "Aquarius" sequence and continuing on to the marvelous set pieces for "Manchester England," "Ain't Got No," "I Got Life," and best of all, the "Electric Blues"/"Hare Krishna" fantasy which shows lovers John Savage and Beverly D'Angelo literally flying through their own wedding ceremony. (BTW, the woman singing "Aquarius" in the film's opening is not Melba Moore, but Ren Woods- a wonderful singer-actress seen a lot on TV in the 70's, and star of the Los Angeles production of "The Wiz.") The opening Twyla Tharp corps-de-ballet shot right on the Central Park grounds- with Woods' solo in a dizzying 360 camera pan- is an awesome start to a rock-infested musical. Ms. Moore (who performed in the original Broadway HAIR) appears later in the film singing "3-5-0-0" with Ronnie Dyson in the war protest scene shot in Washington, DC. And there are moments- like the "Walking In Space" basic training sequence or the simple close-up on Cheryl Barnes's torch solo "Easy To Be Hard-" which are just plain astonishing.
