As the rest of Catfish Row prepares for the church picnic on nearby Kittiwah Island, Sportin' Life again offers to take Bess to New York with him; she refuses. He attempts to give her some "happy dust" despite her claims that she's given up drugs, but Porgy grabs his arm and scares him off. Sportin' Life leaves, reminding Bess as he goes that her men friends come and go, but he will be there all along. Bess and Porgy are now left alone, and express their love for each other ("Bess, You Is My Woman Now"). The chorus re-enters in high spirits as they prepare to leave for the picnic ("Oh, I can't sit down"). Bess is invited to the picnic by Maria, but she demurs as Porgy cannot come (due to his disability, he cannot get on the boat), but Maria insists. Bess leaves Porgy behind as they go off to the picnic. Porgy watches the boat leave ("I got plenty o' nuttin" reprise).
