Two big Broadway hits, a program of show tunes from Broadway musicals, a classic absurdist comedy ("Waiting for Godot," see story on today's Arts Section cover), a dark drama by Horton Foote and two separate series of one-act plays are featured on this week's theater calendar, along with a murder mystery event.

- MUSIC OF THE NIGHT, featuring nearly 20 solos and duets from both stage and screen, will showcase the talents of two of Brigham Young University's most successful music/dance/theater alumni - David and Amy Barrus.The program, part of BYU's ongoing Entr'Acte series, will be performed at 7:30 p.m. April 8-11 in the Pardoe Drama Theatre of the Harris Fine Arts Center.

Each evening, the various segments will focus on different aspects of the couple's lives and careers: Broadway songs from their years as BYU students and at the Sundance Summer Theatre; music from their performances at Walt Disney World in Florida; a musical retelling of their romance and marriage; a section dedicated to David Barrus' father, the late Clyn Barrus, former director of the BYU School of Music, and a look at their future and their desire to be a musical family.

David recently concluded a long-run appearance as Gaston in "Beauty and the Beast" at Disney World/MGM Studios, where Amy was appear-ing as Ariel in "The Little Mermaid." This summer, Amy Barrus will have the title role in the Sundance production of "Gypsy" and David will be performing at Lagoon.
