Cabin in the Sky

In 2016 Encores produced a concert of Cabin in the Sky. Ruben Santiago-Hudson and Jack Viertel tried to cut the condescending material from Root's original book. Critics remained unimpressed with the "religious fable" despite the jazzy score. The show is best remembered for the starry 1943 film. The film is enjoyable but only kept three songs from the stage show.

Clips:
Ethel Waters singing the hit song "Taking a Chance on Love."
Lena Horne singing "Ain't It The Truth" in a bath tub. The scene was cut by the censors.

Porgy and Bess

When Porgy and Bess returned to Broadway in 2011 it caused controversy. Director/adapter Diane Paulus had overseen multiple revisions to the libretto. Stephen Sondheim wrote the New York Times to express his disapproval.

"She fails to recognize that Porgy, Bess, Crown, Sportin’ Life and the rest are archetypes and intended to be larger than life and that filling in “realistic” details is likely to reduce them to line drawings.... let it not be called “The Gershwins’ Porgy and Bess,” nor even “The Gershwin-Heyward Porgy and Bess.” Advertise it honestly as “Diane Paulus’s Porgy and Bess.” And the hell with the real one."

In Paulus's defense the work had already undergone major revisions within the Gershwin's lifetime. Any producer seeing the "real one" has many versions to choose from. The three act opera from 1935, the two act musical from 1942, the two act opera from 1952, and various attempts to dial up or down the characters dialects. None of these versions diminish the power or importance of the work... though I wouldn't recommend doing it with an all white cast like they tried in Switzerland.
