The show is by the composer Joshua Salzman and the bookwriter-lyricist Ryan Cunningham, who previously teamed on the Off-Broadway musical I Love You Because.

The hour-long concert will feature Kate Wetherhead (Spelling Bee, Legally Blonde), Colin Hanlon (Rent, I Love You Because), Michael Holmes (Oklahoma, The Producers), Salzman on piano and Cunningham as Esther's Uncle Mordechai.

According to press notes, the show "follows Esther, a lovable cow-milker's niece, who rises from being the poorest girl in her village to Queen of Persia, after the King chooses her during a spectacular beauty pageant. Esther quickly learns that life as a queen has as many problems as her life in the village, when the King's advisor, Haaman, threatens her people."

Cunningham and Salzman are graduates of the NYU Graduate Musical Theatre Writing Program and participants in the BMI-Lehman Engel Musical Theatre Workshop, where the show originated. They made their television writing debut this year creating songs for Disney's "Johnny and the Sprites" starring John Tartaglia. Salzman served in the music departments of Wicked and All Shook Up and is currently on faculty at The American Musical and Dramatic Academy.

Now in its ninth year, Musical Mondays Theatre Lab, founded by Bick Goss, develops new works for the musical theatre. Musicals Tonight!, run by Mel Miller, presents staged concerts, primarily of neglected musicals from the past. The McGinn/Cazale Theatre is located on Broadway at 76th Street, on the third floor. Admission is $10. For reservations call (212)989-6706.
