The summer night “smiles” three times: on youth, on fools, and on elders. Such is the premise of A Little Night Music. Based on Ingmar Bergman’s 1955 film, Smiles of a Summer Night, the Stephen Sondheim musical follows the lives of several mismatched couples in the early 1900s. It’s most famous song is “Send in the Clowns,” which Judy Collins and Barbra Streisand both recorded and turned into pop hits. The production will come to the stage of Spreckels Performing Arts Center in Rohnert Park, Thursdays through Sundays, February 10–26. Shows will be held at 7:30 p.m., except for Sundays, when they will be at 2 p.m. Tickets are $32–$36 for adults or $12 for ages 17 and younger, and may be purchased at tinyurl.com/2s39a4y8.
