Nearly 700 attendees and headliners Robin Williams and Dana Carvey made the Comedy for Kids with Autism benefit at the Regency Center an unforgettable night. Adding to the night's success were Sammy Hagar and Lawrence Goldfarb, who surprised the audience when they jumped on stage and each pledged $50,000 to Oak Hill School and the Ryder Foundation. Marin County's Oak Hill School provides an integrated therapeutic education for children with autism and other developmentally based learning challenges.
