Twitter Watch: Sara Bareilles Performs Part of Your World, Cut Song, and More at WAITRESS

Audiences at tonight's preview of WAITRESS got to see a very special performance when part of the set for the diner stopped working. While the show was paused so that the crew could make the necessary adjustments - the show's Grammy nominated composer/lyricist Sara Bareilles got on stage to sing a cut song from the show as well as "Part of Your World" - a Disney classic by Alan Menken and Howard Ashman.

Bareilles also took some time to take selfies with the audience.

Audience members inside the Brooks Atkinson Theatre took to social media to share their excitement of seeing Bareilles perform live. Check out some videos, photos, and social media buzz below!
