Directed by Gary Daigneault, with musical direction by Scott Clinkscales and choreography by Lisa Goldberg, the cast includes veteran favorites as well as talented newcomers to the Theatre 29 stage. Tickets are $10 to $15. The final performances will be held at 7 p.m. Saturday with a Sunday matinee at 2:30 p.m. For reservations, visit theatre29.org or call 760-361-4151.
