Jane, but not plain

IS there anything sexier than a beautiful woman in a slinky dress perched atop a piano?

Anyone who saw Michelle Pfeiffer in “The Fabulous Baker Boys” knows the answer — and it’s only confirmed by the opening of “Jane Krakowski Has Sold Out…Tickets Available.”

This talented performer knows her strengths — those who’ve seen her in the shows “Nine” and “Damn Yankees” as well as TV’s “30 Rock” know them, too — and she exploits them very entertainingly in her cabaret debut.

“I love double-entendres,” she proclaims, before a rendition of Eubie Blake and Andy Razaf’s “Handy Man” that manages to make the most explicit current R&B songs seem tame by comparison.

With Marilyn Monroe-style sexiness, she performs “Diamonds Are a Girl’s Best Friend,” albeit in an unconvincingly hip-hop fashion.

More successful is her version of “Zip” from “Pal Joey,” featuring hilarious new lyrics for the age of Twitter by that current go-to team for novelty songs, Marc Shaiman and Scott Wittman. And she reprises her sultry “A Little Brains, a Little Talent” from “Damn Yankees” (although some of us were hoping for “Whatever Lola Wants.”)

Although there’s a smattering of standards by the likes of Cole Porter, Jerome Kern and Irving Berlin, the show’s highlights come with the more offbeat choices. “When I Get Low I Get High,” for instance, takes on an entirely new meaning when combined with Oscar Levant and Stanley Adam’s subversive “Wacky Dust” (yes, it’s about what you think). “Thirteen Men,” taken from an Ann-Margret TV special, is a prime piece of ’60s-era kitsch. And “Rubber Ducky,” accompanied by the star blowing bubbles into the audience, makes a literally effervescent encore.
