The Drowsy Chaperone

Bob Irvin directs perhaps his most perfect cast ( Deane Calvin, Joe Hart, Brianne Hidden-Wise, Analise Langford-Clark, Daniel W. Slauson, Corey D. Winfield and a host of others) in this musical within a comedy as a lonely, obsessive theater-lover (Slauson) conjures a musical in his mind (and on stage) while listening to a recording of his favorite show. F, Sa, Su 8pm. Through 9/8. $5-$15. Fair Oaks Theatre Festival at the Veterans Memorial Amphitheatre, 7991 California Ave. in Fair Oaks; (916) 966-3683, www.fairoakstheatrefestival.com.
