Frank and his boys

These guys weren’t “Mad Men,’’ but they were oh-so-’60s. Frank Sinatra, Sammy Davis Jr., Dean Martin, and Joey Bishop open their ring-a-ding-ding gig tonight at the Stoneham Theatre. “The Rat Pack Is Back’’ pays tribute to the iconic Vegas and Hollywood quartet through the talents of Brian Duprey (Sinatra), Kyle Diamond (Davis), Mickey Joseph (Bishop), and Drew Anthony (Martin). The show is coproduced by Sandy Hackett, son of Buddy. Tonight at 7:30 (through July 26). $48, $44 seniors. Stoneham Theatre, 395 Main St., Stoneham. 781-279-2200. www.stonehamtheatre.org
