Jane Krakowski may be making her cabaret debut, but she has all the skills that cabaret requires and needs to be a little less self-deprecating about it.  She knows how to use her “sexuality,” as her 30 Rock character Jenna Maroney puts it, and can sing all kinds of sexy, from silly to femme fatale. She’s also one hell of a belter, and she could let that loose a little more often.

One of the evening’s highlights, a rewrite of “Zip” to reflect the Twitter age (new lyrics by Marc Shaiman and Scott Wittman), comes a bit too soon. It’s absolutely hilarious, and Krakowski delivers it with a rapid-fire delight worthy of Rosalind Russell.

In a tip of the hat to Gwen Stefani’s “Rich Girl,” she does a pretty-fly-for-a-white-girl rap to “Diamonds are a Girl’s Best Friend.” She follows this up with a tribute to the cocaine-fuelled days of Studio 54, in the form of another rapid-fire number, Oscar Levant’s “Wacky Dust.”

She’s got great timing, a great voice, and a solid act that just needs a little more shaping (maybe she could get Scott Wittman in for a tune-up?).  What she really needs to stop doing, is wondering aloud how anybody knows who she is. Jane, dear, you’re on one of the biggest hits on television, and not for the first time (remember Ally McBeal?). Plus, perhaps more pertinently for this crowd, you have a freaking Tony (for Nine). We know who you are. We love you! Relax and enjoy it!
