The show is scheduled to run through Sunday, and stars Helen Hayes Award-nominee Kate Baldwin and James Clow, who has been on Broadway in "Assassins," "Wonderful Town," and "Company," among others, Playbill reported.
Baldwin has appeared on Broadway in "Wonderful Town," "Thoroughly Modern Millie" and "The Full Monty."
The play was adapted from a short story by Steven Vincent Benet called "The Sobbin' Women," parodying the legend of the "Rape of the Sabine Women."
The 1982 Broadway show, written by Lawrence Kasha and David Landay, starred Debby Boone and the late David-James Caroll.
The original show music is by Gene de Paul with lyrics by Johnny Mercer. The current St. Louis production features new songs by Al Kasha and Joel Hirschhorn.
The Muny says the tale is "the saga of seven backwood brothers and their seven blushing sweethearts from town. Add an abduction, an avalanche and a seven-shotgun wedding, and you've got a vigorous evening of theater to long remember."
