If you went to see Train perform at The Fillmore on Sunday night, you got a Giant(s) surprise: Barry Zito and Matt Cain on stage with the band.

Zito and Cain were invited to close out Bay Area natives Train’s sixth and final set in the City, joining in to sing “Save Me, San Francisco” and “Don’t Stop Believin’.” Their rousing rendition of the former can be heard above.

“So great,” Zito told the AP afterward. “It was a lot of fun, with Cainer up there. All good.”

Cain’s wife, Chelsea, filmed the performance and we can only hope she uploads her footage too; we couldn’t find their version of “Don’t Stop Believin'” on YouTube. (UPDATE: Vigilant reader alohasteve tracked down video of said performance. Check it out below.)
