The cast will gather from 3-7 PM on Frisbee Hill — located just north of the Sheep Meadow Café — to honor the International Day of Peace. The public is invited to partake in the free event and "share flowers, stories, food and music in commemoration of the global holiday honoring peace and unity."

"When we first heard about the International Day of Peace, we knew it would be a great opportunity to further spread the message of peace and harmony that we've been advocating in Hair," said cast member Andrew Kober in a statement. "The 'Be-In' is a chance to gather in the park as a community and spend some time together on love and unity."

The United Nations' International Day of Peace is a global holiday where individuals, communities, nations and governments highlight efforts to end conflict and promote peace.

As previously reported, the Public Theater announced that Hair will arrive on Broadway in 2009. The tribal love-rock musical penned by James Rado, Gerome Ragni and Galt MacDermot concluded its extended engagement at the Delacorte Theater Sept. 14. The Public has not confirmed casting, dates or a theatre for the Broadway transfer.
