Sara Bareilles Saved The Day With An Impromptu Performance At "Waitress"

    Turning lemons into lemonade, amiright?

    Waitress, a new musical production starring Jessie Mueller, is currently in previews on Broadway.

    To make matters even better, all of the music and lyrics for the show were created by the lovely Sara Bareilles.

    At last night's preview, there was some kind of technical glitch...

    The awesome Jessie Mueller backstage right now! Automation time out (1st time) @sarabareilles is out front singing!

    ...so Bareilles hopped on stage to save the day!

    The singer-songwriter gave an impromptu performance of the iconic song from The Little Mermaid, "Part of Your World."

    And she also sang "Down at the Diner," which is apparently a song from Waitress that ended up getting cut.

    Waitress had some technical difficulties, so @SarahBareilles sang a deleted song from the musical #waitressmusical

    It looks like she even answered some questions while she was up there.
