The current revival, directed by Arthur Laurents (who wrote the show’s book), “had been touted for the fact that some songs and dialog performed by its Puerto Rican characters would be delivered in Spanish.” But as of this week, “A Boy Like That” has reverted to the original English, as have parts of “I Feel Pretty.” Laurents says that the use of Spanish in the show “was an experiment …an ongoing process of finding what worked and what didn’t.”
