Brad Paisley continued his long-running support of charitable causes on Saturday (11/11), taking part in the Michael J. Fox Foundation’s annual “A Funny Thing Happened on the Way to Cure Parkinson’s” gala in New York City. The benefit gala brought together nearly 1,000 guests to raise funds for Parkinson’s disease research, including the organization’s founder Michael J. Fox, who actually joined Brad onstage to trade guitar licks on the Chuck Berry classic “Johnny B. Goode.” The event was also a huge success, raising more than $5.2 million to support the cause.
