Neil Diamond called the switchboard at Fenway Park at about 12:30 p.m. ET on Saturday afternoon.

"Hey, I'm here," he said, according to Red Sox officials. "Can I come?"

The 72-year-old, who had flown himself to Boston just for Saturday's 1:10 p.m. game against the Royals, surprised the 35,152 in attendance after the top of the eighth inning and sung the song that's made him synonymous with Fenway Park.

"Sweet Caroline" may have never sounded sweeter.

The Sox stormed back in the bottom of the inning to take the eventual 4-3 win.

Since Diamond's 1969 hit began making regular appearances at Fenway Park in 2002, the song has been considered the Red Sox's song. But this week, with the city suffering from the Boston Marathon bombing tragedy and the Red Sox in Cleveland from Tuesday through Thursday, "Sweet Caroline" was anything but Boston's song.
