Even though the holiday party season has ended, the fetes haven’t. Die-hard nightcrawlers were out in force the other night for Nancy Kane’s birthday party at New York’s AKA.

The Whole Earth Mamas, the band Kane manages, played for the crowd, mostly twentysomethings.

“They sound a lot like Pearl Jam,” said Gerard Schweitzer, who was almost twice the age of most others in the club. “I don’t know, all this music sounds sort of sad to me. You live 20 years longer than these people and you don’t want to be sad anymore.”

Between sets, Mark Ronson, rhythm guitarist and son of Foreigner’s Mick Jones, played deejay while girls in hiking boots and sweatsuit tops settled back in the banquettes. Except Kane, of course, who was busy opening presents, including something called the Beaver Creek Fudge Mountain, a huge mound of fudge decorated with fudge skiers trying to avoid fudge trees.
