I have the movie soundtrack, with the above being all that was sung.
Lyrics were attributed to DuBose Heyward (who wrote the original book, "Porgy" and the screenplay for the movie) AND Ira Gershwin. On the soundtrack album, Cab Calloway stands in for Sammy Davis, Jr. as Sportin' Life.
I've been looking for the movie video for a long time, if anyone has seen it. The music (especially Dorothy Dandridge) is spectacular.....Tiger
