The performance was canceled "to allow the actors a day of rest in the midst of a long string of consecutive performances," according to a show spokesperson.

The 1968 rock musical Hair, which officially introduced Broadway to the counterculture movement four decades ago, began previews at the Hirschfeld March 6.

Diane Paulus stages the new production that began life as a 40th anniversary concert presentation by the Public Theater/New York Shakespeare Festival at the Central Park's Delacorte Theater in 2007. The Public later fully produced Hair in summer 2008 as part of its Shakespeare in the Park season. The al fresco Paulus production extended three times, and now resurfaces on Broadway.

The revival of Hair reunites much of the young cast from the Central Park stagings, including Will Swenson as Berger, Allison Case as Crissy, Kacie Sheik as Jeanie, Bryce Ryness as Woof, Darius Nichols as Hud, Megan Lawrence as Mother and Andrew Kober as Margaret Mead/Dad.

Returning tribe members also include Steel Burkhardt, Lauren Elder, Allison Guinn, Anthony Hollock, John Moauro, Ato Blankson-Wood, Brandon Pearson, Paris Remillard, Maya Sharpe, Theo Stockman, Tommar Wilson, Jackie Burns, Kaitlin Kiyan, Nicole Lewis, Megan Reinking and Saycon Sengbloh. Newly added for Hair's Broadway transfer are Tony nominee Gavin Creel as Claude, Sasha Allen as Dionne and Caissie Levy as Sheila.

The iconic tribal rock musical has book and lyrics by the late Gerome Ragni and James Rado and music by Galt MacDermot.

"With a score including such enduring musical numbers as 'Let the Sun Shine In,' 'Aquarius,' 'Hair' and 'Good Morning Starshine,' Hair depicts the birth of a cultural movement in the 60's and 70's that changed America forever: the musical follows a group of hopeful, free-spirited young people who advocate a lifestyle of pacifism and free-love in a society riddled with intolerance and brutality during the Vietnam War," according to Broadway production notes. "As they explore sexual identity, challenge racism, experiment with drugs and burn draft cards, the 'tribe' in Hair creates an irresistible message of hope, peace and change that continues to resonate with audiences 40 years later."

The Hair creative team includes set designer Scott Pask, costume designer Michael McDonald, lighting designer Kevin Adams, sound designer Acme Sound Partners and choreographer Karole Armitage.
