Of this performance, the Riverfront Times reviewer wrote: "Crosby can sing a lesser-known song such as "Before I Gaze at You Again" and make us wonder why we've overlooked it all these years. She can sing a popular tune like "I Loved You Once in Silence" and make us realize that Frederick Loewe's score is possessed of a haunting quality reminiscent of Schubert." Crosby recently played Mrs. Darling and other characters in the new national tour of Peter Pan alongside Cathy Rigby in the title role, which began performances August 2011 and concluded on April 28, 2013.
