Michael Feinstein and Christine Ebersole

This is your last chance to see a show at standards-bearer Michael Feinstein’s eponymous supper club—at least in its current incarnation at Loews Regency. Feinstein marks the end of both 2012 and his 14-year-old Upper East Side cabaret spot in the company of Broadway star Christine Ebersole, who can really knock out a number.
