Theme: My mom is one - TWINS. Each starred clue is answered by one of a brace of famous real or mythical twins. The crossing theme answer is the other twin of the pair. Further, one of these twins is indicated by a two-word answer in which the second word is a red herring, while the other is a simple one-word name, clued in a way that should specifically identify the specific set of TWINS in question.
17 A. *Edward Cullen's rival for Bella's hand, in the "Twilight" series : JACOB BLACK. I haven't watched this series, so it took a lot of perp help.
2.D. *Biblical birthright seller : ESAU. JACOB's TWIN. Isaac's non-identical twin sons are both frequent crossword denizens. You know the story.
23 A. *She played Michelle on "Full House" : MARY KATE. Tricky, since the roll was shared by both of these TWINS.
11. *"High Crimes" actress : ASHLEY JUDD. As this point, having only half sussed the theme, I'm thinking - wait! The Judd sisters aren't twins! But MARY KATE and ASHLEY Olsen are. They have since grown up, or at least gotten older.
45 A. *Brother of Helen of Troy, some say : POLLUX. I did not know that.
28 D. *Source of an age-old medicinal oil : CASTOR BEAN. CASTOR OIL, of course. I don't recall ever being subjected to this cure. CASTOR and POLLUX in Greek mythology, present a confusing case. Per Wikipedia: "Their mother was Leda, but Castor was the mortal son of Tyndareus, the king of Sparta, and Pollux the divine son of Zeus, who seduced or raped Leda in the guise of a swan (Greek myths concerning divine sex are often vague on the issue of female consent)." That's more than I can comprehend. Better still, Helen also had a TWIN, the unfortunately named Clytemnestra. CASTOR and POLLUX are also the brightest stars in the constellation Gemini, and a pet products brand.
59 A. *Beach Boys title girl : BARBARA ANN. This takes me back to my ute. But back in the day  this was a hit recording for the Regents. The Beach Boys cover came later.
44 D. *"Today" correspondent __ Bush Hager : JENNA. BARBARA and JENNA are the daughters of former President George W. Bush, and clearly non-identical TWINS. They also got older. Here they are with their mom, former first lady Laura Bush.
And the unifier: 64 A. Target Field team, and each pair of intersecting names in the answers to starred clues : TWINS. C.C.'s home baseball team is not having a good year. They play three games against the Tigers next Mon.- Wed.
It took me quite a while to find C.C.'s wavelength. But wow - eight paired, crossing theme entries, with the horizontal elements in perfect symmetry, plus a unifier stacked below the last horizontal theme fill. Also, two TWIN sets are male and two are female. I don't even want to think about what it took to put this together.
Hi gang, a very impressed JazzBumpa here. Let's see what else C.C. has in store for us the rest of the way.
