"Modest Maid," written by Marc Blitzstein. Evidently he wrote it for the great Beatrice Lillie but she never performed it. Charlotte Rae recorded it back int he 1950's. One of my favorite audition pieces, because it's one not heard very often.
Another favorite piece...for auditions or just anywhere. This is by the brilliantly talented Jenny Giering & Sean Barry from their musical "Saint Ex."
A snippet of Ms. Pennywise's rousing anthem from "Urinetown."
Berthe's song from "Pippin."
One of my favorite roles of recent years included this great song from "The Drowsy Chaperone"
The song "First Grade Teacher" from "Crossing Brooklyn" (Music by Jenny Giering/Lyrics by Laura Harrrington)
