On Friday afternoon, Concord Main Street regular Kevin Clark became Twitter-famous when presidential candidate U.S. Sen. Kirsten Gillibrand, a New York Democrat, stopped by to hear him play “Father and Son” by Cat Stevens, one of Gillibrand’s “favorite songs in high school.”

“It was a blast,” Clark said Monday as he continued to play his guitar for passersby in Concord’s downtown Eagle Square during the snowstorm.
