VIDEO: Sara Bareilles and Katharine McPhee Team Up For A WAITRESS Duet

The Tony-nominated musical Waitress by Sara Bareilles is now playing at the Adelphi Theatre in London's West End. This week, Bareilles teamed up with the West End Jenna, SMASH star Katharine McPhee for a duet on the show's signature ballad, She Used To Be MIne. See their performance below!

Based on the 2007 motion picture written by Adrienne Shelly, Waitress is the first Broadway and West End musical in history to have four women in the four top creative team spots. The show features original music and lyrics by Sara Bareilles, a book by Jessie Nelson, direction by Diane Paulus and choreography by Lorin Latarro.

The West End production of Waitress stars Katharine McPhee (Smash) as Jenna, Emmy-nominee Jack McBrayer (30 Rock) as Ogie, Marisha Wallace as Becky, Laura Baldwin as Dawn, Peter Hannah as Earl, David Hunter as Dr. Pomatter and Shaun Prendergast as Old Joe.
