Decca Presents Selections from George Gershwin's folk opera Porgy and Bess consists of two volumes of records, the first from 1940, and the next from 1942.

The 1940 album was the first to record selections from George Gershwin's opera Porgy and Bess as sung by members of the original Broadway cast from 1935.

The only singers involved were Todd Duncan as Porgy and Anne Brown as Bess.

Duncan sang "It Ain't Necessarily So", which is sung in the opera by Sportin' Life.

A few years later, Decca re-released the albums as on LP set entitled Selections from Porgy and Bess in February 1950, (DL 7006), deceptively billing it as "the original cast album" though only selected members of two separate casts participated.
