Here's what's going on today (Saturday, June 28): Western weekend at the Lucas continues with 1969's Butch Cassidy and the Sundance Kid at 3 p.m., and the Josh Brolin/ Russell Crowe remake of 3:10 to Yuma at 7. At Club One, Bay Street Theatre's production of the thriller Bug is live onstage at 8 p.m. Going clubbing tonight? We recommend A Nickel Bag of Funk at Congress St. Social Club, the Accomplices at North Beach Grill, and Roshambeaux at World of Beer. And Dreamend plays along with New Pink Floyd at Sparetime!
