Celebs Support Michael J. Fox’s Charity for a Night of Music & Comedy

Stars collided with rock n' rollers on Saturday night for a night of comedy and music to benefit The Michael J. Fox Foundation for Parkinson's Research.

"It's like Thanksgiving or a holiday, you always look forward to it," Fox said of the evening.

TV star Denis Leary came out for the event and talked to ET about his friend's charity. "It's obviously a great cause and a lot of fun. ... One of the highlights, generally speaking, is when Mike Fox gets up on stage to play with the rock n' roll hall of famers."
