How a Song Will Help Boston

"Sweet Caroline," an unofficial anthem at Fenway Park for more than 10 years now, is way up in popularity in the wake of the Boston Marathon bombings. Sales of the song—sung by Diamond himself at the first Red Sox game after the attacks, and even played at Yankee Stadium in a show of solidarity—are up 597%. And Diamond is donating this week's revenues to bombing victims, the AP reports. Just how many copies of the track sold this week: 19,000, according to Nielsen SoundScan.
