Question: Intiman Theatre Festival has hosted the actress and singer of what nationality?
Related documents: [0]  [DOC] Intiman Theatre Festival in Seattle, Washington, was founded in 1972 as a resident theatre by Margaret "Megs" Booker, who named it for August Strindberg's Stockholm theater. With a self-declared focus on "a resident acting ensemble, fidelity to the playwright's intentions and a close relationship between actor and audience", the Intiman soon called itself as "Seattle's classic theater". Its debut season in 1972 included "Rosmersholm", "The Creditors", "The Underpants", and "Brecht on Brecht". The theater has been host to Tony-nominated Director Bartlett Sher (who served as both a director and artistic director), Tony-nominated actress Celia Keenan-Bolger, and movie actor Tom Skerritt. It was also home to the world premieres of the Tony-winning Broadway musical "The Light in the Piazza", Craig Lucas's "Singing Forest" and Dan Savage's "Miracle!". Lucas also served as the Associate Artistic Director. Intiman won the 2006 Regional Theatre Tony Award. [END]
