Diane Paulus directs the Delacorte staging that reunites much of the 40th anniversary cast of Hair, which played the outdoor theatre in September 2007. The current Shakespeare in the Park presentation — with choreography by Karole Armitage (Passing Strange) — officially opens Aug. 7 and will play an already-extended run through Aug. 31.

In addition to Groff as Claude, Swenson as Berger and Miller as Dionne, Hair also stars Caryn Lyn-Manuel (Sheila), Ato Blankson-Wood (Tribe), Steel Burkhardt (Tribe), Jackie Burns (White Boys Trio/Tribe), Allison Case (Crissy), Lauren Elder (Tribe), Allison Guinn (Tribe), Anthony Hollock (Tribe), Kaitlin Kiyan (Tribe), Andrew Kober (Father/Margaret Mead), Megan Lawrence (Mother), Nicole Lewis (White Boys Trio/Tribe), John M. Moauro (Tribe), Darius Nichols (Hud), Brandon Pearson (Tribe), Megan Reinking (Black Boys Trio/Tribe), Paris Remillard (Tribe), Bryce Ryness (Woof), Saycon Sengbloh (White Boys Trio/Tribe), Maya Sharpe (Tribe), Kacie Sheik (Jeanie), Theo Stockman (Tribe) and Tommar Wilson (Tribe).

The creative team comprises Scott Pask (set design), Michael McDonald (costume design), Michael Chybowski (lighting design) and Acme Sound Partners (sound design).

Featuring book and lyrics by James Rado and Gerome Ragni and music by Galt MacDermot, Hair made theatre history for its rock 'n roll anti-establishment concept.
