Bay seniors whose lifelong love of the USA soars at the sounds of a band trumpeting John Phillip Sousa, should head out to Golden Gate Park today. In the Bandshell on the Main Concourse, there’s a free concert at 1 pm by the Golden Gate Park band. Hard to believe but it’s the 131st season of this summer music staple. If you miss it, you can always hear them any Sunday through October 6. For homebodies, the Geezer recommends a YouTube viewing of “Stars and Stripes”, the stirring stand up and cheer ballet by George Balanchine.
