“A similarly quiet yet touching moment comes during the song “I Need to Know.” In it, young Tarzan (a sensitive Grace Suárez) despairs (…) Suárez delivers the number soulfully, with quiet yearning, in a voice that sounds like it belongs to a boy. A puppet stands in for Tarzan as a child — a choice that might seem simple, but proves effective.

Grace Suárez, an adult woman, plays Young Tarzan, a role originated by a male child actor on Broadway. Suárez’s performance incorporates the use of a primitive Bunraku puppet. Even while operating this puppet with both hands, she maintains facial expressions that display a sense of cherubic curiosity. During the song “When Will I Be Me,” Suárez sings with a bright mix voice that delivers a youthful quality.
