Kevin Mambo had been serving as temporary replacement since May 20, and will now continue through May 31. Mambo was also co-lead with Ngaujah in Fela! on Broadway. Beginning June 2 and for the rest of the run ending June 14, the role of Jonathan will be played by Yaegel T. Welch.

The news follows two recently announced extensions of the play. The Painted Rocks at Revolver Creek will now play through June 14, following previews that began April 21.

The Painted Rocks at Revolver Creek explores the history of apartheid and tells the story of aging farmer and artist Nukain, played by Leon Addison Brown (Cinemax's "The Knick," The Train Driver). Brown's character is inspired by the real life of South African artist Nukain Mabusa.

The cast also features Bianca Amato (Macbeth) and Caleb McLaughlin (The Lion King).

Fugard is the winner of the 2011 Lifetime Achievement Tony Award and previous Signature playwright-in-resident at the Off-Broadway theatre. In The Painted Rocks at Revolver Creek, aging farmer Nukain is approaching the end of a life-long project, that of painting the rocks at Revolver Creek and transforming the land into a colorful garden of painted flowers. According to press notes, "Now, the final unpainted rock, as well as his young companion Bokkie, has forced Nukain to confront his legacy as a painter, a person and a black man in 1980s South Africa. When the landowner’s wife arrives with demands about the painting, the profound rifts of a country hurtling toward the end of apartheid are laid bare."

The design team includes Christopher H. Barreca (scenic design), Susan Hilferty (costume design), Stephen Strawbridge (lighting design), Stowe Nelson (sound design), Barbara Rubin (dialect coach). Linda Marvel is the production stage manager. Casting is by Telsey + Company, Karyn Casl, CSA.
