AP Paul McCartney at Candlestick Park in San Francisco, Aug. 14, 2014. Van Dam, a fan of the Beatles, grew out his hair when he was young and living on Cape Cod when the band came to the Garden. Joanne Rathe/Globe Staff On the day of the concert, Van Dam went into Boston, where girls and young women were gathering around the Garden. Handout Van Dam was swarmed by dozens of screaming girls who mistookhim for McCartney, and his sweatshirt was torn off. Joanne Rathe/Globe Staff Van Dam crawled out of the crowd and ran, the girls following him until he hid under a car and they passed. Joanne Rathe/Globe Staf Now 67, Van Dam's gray hair remains distinctly Beatleseque. He will take part in the West End Museum's celebration for the concert's 50th anniversary this weekend.
