The three expectant mothers will perform at 3 PM June 4 and 7 PM on June 5.

DJ Salisbury will direct the trio in their first appearance with the cabaret—Van Duyne and Maloney are first-time mothers, and Kostival was supposed to appear in the 2006 production of Hot Mamas but went into early labor.

The cabaret  will feature musical direction by Aaron McAllister and  will include music from composers and lyricists Robert Lopez (co-writer of Book of Mormon and Avenue Q), his wife Kristen Anderson-Lopez, Mary-Mitchell Campbell (musical director of The Addams Family), Gavin Creel (Claude in Hair), Georgia Stitt, Steve Marzullo, Brian Cimmet, Sara Wordsworth, James Allen-Ford, Jodi Darling, Steven Silverstein, Emily Joy Schiff-Glen, Bill Augustin, Andrew Abrams, Amelia DeMayo, Jill Abramovitz, Brad Alexander, Tesha Buss, Leslie Becker, Lorraine Kollar, Denver Casado, Betina Hershey, Amanda Yesnowitz and Deborah Abramson.

The show’s original creators include Mary-Mitchell Campbell, Tesha Buss, Alison Cimmet, Jodi Darling and Carol Linnea Johnson.

Part of the proceeds from the performance will benefit Artists Striving To End Poverty.
