Michael J. Fox hosted a gala benefit for his Foundation for Parkinson’s Research called “A Funny Thing Happened on the Way to Cure Parkinson’s” at Roseland Ballroom. The comedy night drew 900 guests, including Fox’s pals from TV and movies, who joined New York A-listers to raise big bucks for—what else?—Parkinson’s research. In the power crowd: Fox’s wife Tracy Pollan, Jon Stewart, Denis Leary, Ellen Barkin, Kevin Kline and Phoebe Cates, and Joan Rivers.
