NEW YORK (AP) — A new concert piece about slain gay rights leader Harvey Milk by Tony Award-nominee Andrew Lippa will have its world premiere in June in San Francisco.

Producers said Monday that "I Am Harvey Milk" — part choral, part theater — will be performed June 27-28 as part of the San Francisco Gay Men's Chorus 35th Anniversary Celebration concert.

Lipa, who wrote the music and lyrics for Broadway's "The Addams Family" and the upcoming "Big Fish," will play Milk. The 300-member chorus will be joined by Tony-winner Laura Benanti.

Milk became one of the first openly gay men elected to public office in the United States when he won a seat on the San Francisco board of supervisors in 1977. He was assassinated a year later.
