AUDIO: WAITRESS' Sara Bareilles Warns Theatre-Goers to Silence Phones with Original Tune

Sara Bareilles has tackled Broadway with the new musical WAITRESS - and now she's tunefully taking on the issue of cell phones in theaters.

The singer-songwriter has penned an original, 40-second song urging audience members to silence their devices ahead of the curtain, insisting "no one's going to like you if your phone rings."

As of now, there's no official word on whether the tune will play ahead of each performance of WAITRESS - regardless, you can check it out below!

On the inception of the song, Bareilles told The Associated Press: "The team and I spoke after the show, and I suggested a cellphone announcement that I would write and sing myself. I decided to rewrite the words to a song of mine called 'Cassiopeia,' and try to make something funny, in the style of the show, but that would still get the point across...I wrote it in an evening and recorded it at home. It seems to have done the trick, although the errant cellphone still makes me crazy."

Based upon 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 Bareilles, choreography by Lorin Latarro and direction by Tony Award-winner Diane Paulus.
