The Theatre department will revive its Children's Matinee series on Saturday, March 12, with a production of Miss Nelson is Missing. There will be two performances at 11 a.m. and 2 p.m. in the University Theatre. Performers and technicians from the California Theatre Company will stage Miss Nelson is Missing, a musical comedy about a clever teacher who masquerades as a nasty substitute in order to teach her class just what a good and fair teacher she is.
