The musical “Oklahoma” opened on Friday at Theatre 29. The musical was first performed 75 years ago and is a perennially popular show. Directed by Charles Harvey, this tale of star-crossed lovers—a charming cowboy and a winsome farmer’s daughter in the wild frontier—will run four weekends through March 31. Performances are at 7 p.m. on Fridays and Saturdays, and 2:30 p.m. on Sunday afternoons. Tickets are $10 to $15 and are available at the Theatre 29 Box office, at theatre29.org, or by calling 760-361-4151.
