Neil Diamond is happy that his song, "Sweet Caroline," offers comfort in the wake of the Boston Marathon tragedy. A staple of Red Sox games, other cities have taken to playing the long of late to show solidarity with Beantown.

Saturday, during the seventh inning stretch at Fenway Park, fans were given a surprise performance from Diamond himself, as he led them in an inspiring rendition of the Boston tradition.
