Porgy and Bess — which features some of the greatest songs in musical theatre, including “Summertime,” “I Got Plenty o’ Nothin’” and “It Aint Necessarily So” — premiered Oct. 10, 1935, at New York’s Alvin Theatre. With a score by George Gershwin, lyrics by his brother Ira and book-writer DuBose Heyward, Porgy and Bess was based on Dubose and Dorothy Heyward’s novel "Porgy."

Set in the fictional Catfish Row, South Carolina, the show was the first time the musical form attempted to reflect African-American working-class experience. Since its premiere, the show has attained opera status. Nunn’s £3 million (about $5.5 million) production features a 40-strong cast and a 20-piece orchestra.
