The last time Willie Nelson was in the Bay Area, he pulled his white van through a huge crowd at Outside Lands in Golden Gate Park, hopped onstage with his beat-up guitar and sang a perfect set of hits to a crowd as diverse as San Francisco used to be. Rednecks, hipsters, tech bros, fluff girls, stoners, parents, babies—everyone loves Willie. Even John Stamos, from TV’s Full House, spontaneously joined the band on bongos, and Bob Weir showed up to sing “Roll Me Up and Smoke Me When I Die.” In short: there’s no telling what will happen when Willie rolls through on Friday, Dec. 13, at the Wells Fargo Center. 50 Mark West Springs Road, Santa Rosa. 8pm. $46—$86. 707.546.3600.
