In JULIE'S GREENROOM, Miss Julie (Julie Andrews) and her assistant, Gus (Giullian Yao Gioiello), teach a group of five young kids called "Greenies" all about the performing arts and putting on a show at her own studio. All the youngsters arrive at the greenroom with their own interests related to the stage: Peri (Stephanie D'Abruzzo) hopes to be a star, Spike (Frankie Cordero) excels at crafting rhymes and lines, Hank (John Tartaglia) is a piano virtuoso, Fizz (Dorien Davies) is awed by the costumes and make-up, and Riley (Jennifer Barnhart) favors the mechanics behind the whole thing. Together they learn all about crafting and staging a musical performance from Miss Julie and her special guests -- including Alec Baldwin, Josh Groban, and Carol Burnett -- so they can put on their own original show that borrows elements from dance, mime, improv, and numerous other art forms.
