Grammy winning singer-songwriter Jason Mraz will make his Broadway debut in the role of Dr. Pomatter in Waitress, starting November 3 for a limited ten-week engagement, according to Playbill.

Waitress features original music and lyrics by 6-time Grammy nominee Sara Bareilles, a book by acclaimed screenwriter Jessie Nelson, and direction by Tony Award winner Diane Paulus. Mraz is already familiar with the score of the hit Broadway show; he appeared in two songs on composer Sara Bareilles’ 2015 album, What’s Inside: Songs from Waitress. Both tracks on which he appears as a guest artist, “Bad Idea” and “You Matter to Me,” are performed in the show by Dr. Pomatter and Jenna, who is played by Betsy Wolfe.

Mraz will succeed original cast member Drew Gehling, who recently stepped in for a return engagement. Other cast members include Tony nominees Christopher Fitzgerald and Will Swenson as Ogie and Earl, respectively, Eric Anderson as Cal, Maia Nkenge Wilson as Becky, Caitlin Houlahan as Dawn, and Larry Marshall as Joe. Tony winner John Cullum (Shenandoah and On the Twentieth Century) will take over the role of Joe starting October 5.

The musical’s website details the new show:

Inspired by Adrienne Shelly’s beloved film, WAITRESS tells the story of Jenna, a waitress and expert pie maker who dreams of a way out of her small town and loveless marriage. A baking contest in a nearby county and the town’s new doctor may offer her a chance at a fresh start, while her fellow waitresses offer their own recipes for happiness. But Jenna must summon the strength and courage to rebuild her own life.

After a number of mysterious tweets hinting at his addition to the cast from collaborator Sara Bareilles, Mraz himself confirmed the news with the following tweet and video:
