For nearly two decades, Jonathan Poretz, the Bay Area's favorite crooner, has brought together Frank Sinatra and Bobby Darin in his highly acclaimed show. Backed by his super swingin' Mini-Big Band, Poretz powers through the very best of the Great American Songbook in "Sinatra & Darin: 200 Years of Swagger and Swing!" — a wild cool and swinging salute to two of the biggest legends in show business.
