Songs celebrating California predate Katy Perry, Tupac and Dr. Dreand even the Beach Boys . By a good century.
The San Francisco exhibition "Singing in the Golden State" has collected songs -- from the Gold Rush to the vaudeville era -- name-checking the state and its events. Its sheet-music collection includes the 1913 song "I Love You, California," as well as "California Flood Mazurka," which commemorates the 1862 Sacramento flood.
The songs evoke pre-radio, pre-television parlor get-togethers that helped spread news about California. The show at the Society of California Pioneers, 300 Fourth Street, includes visually evocative sheet-music covers, sound recordings and instruments
The show runs into December. Hours are 10 a.m.-4 p.m. Wednesdays-Fridays and the first Saturday of each month. For information, see the Society of California Pioneers website or call (415) 957-1849.
