Off Broadway’s Public Theater will beef up its Rialto producing duties for the upcoming Broadway transfer of “Hair,” the current Shakespeare in the Park offering now confirmed to hit the Main Stem this season.

The Public will be a managing producer of the Broadway incarnation with producing partner Elizabeth I. McCann, who teamed with the org last season to move tuner “Passing Strange” to the Rialto.

“The Public is going to take a very active role in producing again,” said Public a.d. Oskar Eustis. “We should be taking responsibility not just for the quality of the show itself but also for making sure it reaches the broadest and most diverse audience it can.”

The level of Public’s involvement in “Hair” will be a step up from the org’s participation in “Passing Strange,” which struggled to attract auds despite critical praise and Tony noms.

Key Public staffers involved in Rialto operations will be Eustis, exec director Andrew D. Hamingson and associate producer Jenny Gersten. A new addition to the Public, Hamingson was formerly the managing director at Off Broadway’s Atlantic Theater, where he was involved in Rialto transfers of Atlantic shows “Spring Awakening” and “The Lieutenant of Inishmore.”

No timeline for the Broadway version of “Hair” has been set. Production ends its extended run at the Delacorte Theater on Sunday. Since the tuner has not yet booked a Rialto venue, a spring berth seems likely.

The 1967 flower-power musical originated at the Public before a 1968 Broadway run that lasted four years. Current revival, helmer Diane Paulus’ fully staged version of a concert performance that ran briefly in the Park last year, has attracted major crowds and industry attention since it began perfs July 22.
