The suave and seductive crooners that led the Rat Pack may all be long gone, but their signature tunes will ring out when they’re transported from the nightclubs of Las Vegas to the stage at Signature Theatre. Three familiar studs of the Signature stage—James Gardiner (The Last Five Years, Chess), Bobby Smith (Road Show, Simply Sondheim), and Paul Scanlan (Simply Sondheim, Sunday in the Park with George)—will be cracking wise at this limited engagement cabaret performance in the arts complex’s Shen space. Indoor smoking may be banned nationwide but libations will flow freely, just like Dean and Frank would have demanded. For this week, the Shen is set up like a spot on the Strip with table seating and a bar in the theater. Slick back your hair with pomade, shine those wingtips, and tell your dame to put on her best red lipstick as you get transported back to the ’60s to the sound of “That’s Amore,” “King of the Road,” and “I’ve Gotta Be Me.” The production runs April 19 to 23 at Signature Theatre, 4200 Campbell Ave., Arlington. $35.
