Famed director Hal Prince endorses Leslie’s CD Let My Song Fill Your Heart (Original Cast Records). “Leslie Giammanco’s CD celebrates a golden period in American Musical Theatre. Her choices are just that: Choice. Some of the selections are standards, some are little known, but wonderful. Larry Grossman’s and Hal Hackady’s Mama a Rainbow, Jerome Kern and Ira Gershwin’s Long Ago (and Far Away), and Jerry Herman’s It Only Takes a Moment, are just three favorites. Ms. Giammanco is currently a member of the New York Production of  “The Phantom of the Opera” and represents it eloquently.”
