Our fascination with celebrity Jonathan Tolins’ off-Broadway hit “Buyer & Cellar” continues through Sunday, May 10 in an extended engagement at The Old Globe Theatre’s White Theatre. The sole performer, appealing Broadway actor David Turner, insists at the outset that nothing is real except the setting – Barbra Streisand’s basement mini-mall – as limed in her 2010 book, “My Passion for Design.” Turner portrays Alex More, an unemployed Hollywood actor hired to be Streisand’s shopkeeper. The diva finally appears – and with subtle changes in posture and facial expression, Turner becomes Streisand. Among others, he also portrays his own doubting boyfriend and Streisand’s husband, James Brolin. As he maintains the items in Streisand’s shops, More becomes increasingly convinced that the needy singer/actor is actually his real friend and also his eventual entre into the kind of showbiz career he deserves. “Buyer & Cellar” is for all who idolize, who love one-person shows and who long for an insider’s view. Considering there is no one like Barbra, the show has a built-in audience. “Buyer & Cellar” continues Tuesdays through Sundays through May 10 in the Sheryl and Harvey White Theatre at the Conrad Prebys Theater Center, 1363 Old Globe Way, Balboa Park. Find tickets at theoldglobe.org or (619) 23-GLOBE.

Cast as Mrs. Lovett is Grimsley’s real-life wife, Luretta Bybee.
