Howard Ashman and Alan Menken’s beloved tale centers on young Ariel, who yearns to venture beyond her underwater home and go where the people are, up on land. The enchanting musical includes tunes from Disney’s 1989 animated film, such as “Under the Sea,” “Kiss the Girl” and “Poor Unfortunate Souls.” Theatregoers of all ages will want to be part of this world.
