Boston got a "sweet" morale boost on Saturday, courtesy of legendary crooner Neil Diamond. During the 8th inning of the Red Sox's baseball game against the Kansas City Royals, Diamond took to the field in Fenway Park to lead the crowd in a stirring rendition of his classic 1969 hit "Sweet Caroline."

Diamond's live rendition of "Caroline" (which climbed to no. 4 on the Billboard Hot 100) sparked an enthusiastic sing-along in Fenway, as the 35,000 in attendance echoed every word and erupted into a chant of "U-S-A" at the song's conclusion.

The song, which has been adopted as the Red Sox's anthem and played during the 8th inning of every home game since 2002, has rung out at sporting events across the country after Monday's Boston Marathon bombings, in efforts to give solace to those affected by the tragedy.

“What resonates for me ... is the way music can offer comfort to people in times of joy or sorrow,” Diamond, 72, told the L.A. Times at Thursday's Rock and Roll Hall of Fame induction ceremony. “With a tragedy like this, there are no words, but if people can find healing in music, this is the reason I’ve been doing this for the last 50 years. It goes beyond what I ever imagined.”
