Iconic American singer Neil Diamond performed his hit "Sweet Caroline" at the Red Sox game as fans returned to Fenway park on Saturday (April 20) following a turbulent few days in Boston after the marathon bombing and the manhunt for the suspect that followed.

During the eighth inning, Diamond took over the field and sang "Sweet Caroline," a song that has been a Fenway staple for years. According to reports, Diamond showed up on his own volition.

On April 16, the day after the Boston Marathon bombings, the New York Yankees (longtime Red Sox rivals) played "Sweet Caroline" during their home game, preceeded by a moment of silence as a tribute to the victims.

Major league ballparks around the United States paid tribute to the victims and those affected by the Boston Marathon bombings by playing "Sweet Caroline" over the loud speakers at the ballpark, mainly in the middle of the eighth inning.

Other bands have paid tribute to those affected by the Boston Marathon bombings, like the Dropkick Murphys, who raised over $100k for the victims by selling their "For Boston" t-shirt.
