Olivier Award winner Ruthie Henshall (Chicago, She Loves Me) will join London Waitress star Marisha Wallace on the stage at the Adelphi Theatre for Waitress' London Cast Album Karaoke Night April 10. As is the case with the Broadway production, London audience members can sign up before the curtain for the chance to sing one minute of any song from the musical.

Participants will be accompanied by musical director Katharine Woolley.

Alongside Katharine McPhee as Jenna, the London production of Waitress stars Jack McBrayer as Ogie, Wallace as Becky, Laura Baldwin as Dawn, Peter Hannah as Earl, David Hunter as Dr. Pomatter, and Shaun Prendergast as Old Joe.

The company includes Kelly Agbowu, Laura Baldwin, Piers Bate, Nicole Raquel Dennis, Michael Hamway, Peter Hannah, David Hunter, Stephen Leask, Jack McBrayer, Chris McGuigan, Katharine McPhee, Olivia Moore, Nathaniel Morrison, Sarah O’Connor, Leanne Pinder, Shaun Prendergast, Charlotte Riby, Marisha Wallace and Mark Willshire.

The love story of an exceptional pie-maker and an OBGYN, Waitress features a score by Sara Bareilles (Love Song, Brave), a book by Jessie Nelson (I Am Sam), direction by Tony Award winner Diane Paulus (Pippin, Finding Neverland), and choreography by Lorin Latarro.

The production is currently playing on Broadway and touring the U.S. The show will have its Australian premiere in 2020 at the Sydney Lyric Theatre.
