These days, if a movie musical doesn’t incorporate oversized plants exclaiming “Feed me, Seymour!” or a bluesy duo clad in trendy shades and super-sweet suits, most people don’t bother. But the 1960s were a much different time, and even the American Film Institute agrees that The Sound of Music was a little more relevant. It’s also a gas to sing along to. Test your vocal skills with a crowd of other Julie Andrews fans at the Sing-a-Long ‘Sound of Music’ on Saturday, Oct. 29, at the Sixth Street Playhouse. 52 W. Sixth St., Santa Rosa. 7pm. $15–$25. 707.523.4185.
