VIDEO: WAITRESS' Sara Bareilles 'Over The Moon' About Being Welcomed To Broadway

Five-time Grammy nominee Sara Bareilles is the latest pop star to have a go at writing a Broadway musical, and she sure learned quickly how it's done. Her wonderfully textured, Tony-nominated, character-driven score for Waitress ranks as one of the top debuts of the last Broadway season and musical theatre fans are hoping she'll come back with more.

While recording the recently released Waitress original Broadway cast recording, Bareilles admitted that her internal, little self is "over the moon" with the experience of having written the score for a hit Broadway show.

She participated in community theatre while growing up, but being invited into the Broadway community is something she never dreamed would happen.

WAITRESS, which was nominated for four Tony Awards this year, opened in April at the Brooks Atkinson Theatre after a sold-out limited engagement at the American Repertory Theater (A.R.T.) at Harvard University in Cambridge, MA.

Based on the 2007 motion picture written by Adrienne Shelly, Waitress is the first Broadway musical in history to have four women in the four top creative team spots, with book by Jessie Nelson, score by five-time Grammy Award-nominated singer-songwriter Sara Bareilles, choreography by Lorin Latarro and direction by Tony Award-winner Diane Paulus.

In Waitress, Jenna is a server and expert pie maker stuck in a small town and a loveless marriage. Faced with an unexpected pregnancy, Jenna fears she may have to abandon the dream of opening her own pie shop forever... until a baking contest in a nearby county and the town's handsome new doctor offer her a tempting recipe for happiness. Supported by her quirky crew of fellow Waitresses and loyal customers, Jenna summons the secret ingredient she's been missing all along - courage.
