Menotti's The Unicorn and two other creatures

The kids and I saw the Bowen McCauley Dance performance of Gian Carlo Menotti's "The Unicorn, The Gorgon and the Manticore" this afternoon. Some of the dancers, notably the Mystery Man and the Unicorn, visited Milly's preschool a few weeks ago, and she insisted that we buy tickets to the performance. It was fantastic! I wasn't familiar with the libretto (the only Menotti I know is "Amahl and the Night Visitors"), but it's a fable about art and envy that, on at least some levels, children can understand. And they loved the animals.

Afterwards, Lucy Bowen McCauley, the artistic director, invited the children in the audience to come onstage, and she and the dancers taught them the characteristic movements of each animal and how they corresponded to the music. Nothing against the Gorgon and the Manticore, but the Unicorn was Milly's favorite. Highly recommended for young dancers.

[Aside: Milly is interested in unicorns, and I've been looking for books about them to share with her, with limited success. Can you recommend any unicorn books for younger readers and listeners? Team Unicorn people, I'm looking at you.]
