Neil Diamond thrilled baseball fans in Boston, Massachusetts, by jetting into the city for a surprise performance of his hit Sweet Caroline at a game on Saturday (20Apr13). The singer took an overnight flight from Los Angeles to make it to Fenway Park in time to appear at the Boston Red Sox's first home game since the attacks at the Boston Marathon on Monday (15Apr13). Donning a Red Sox baseball cap, Diamond drew huge cheers as he took to the field to sing the iconic 1969 track, which has become an anthem for the Boston Red Sox and been played at every game at the stadium since 2002. He says, "I was humbled and honoured to be in Boston and to be able to personally thank and express my gratitude to the first responders and law enforcement officers." Every Major League Baseball park across the U.S. has also played Diamond's classic song in tribute to Boston. Diamond's visit came one day after the city was locked down as the police pursued a suspect linked to the Marathon blasts, which killed three people and injured more than 175. Dzhokhar Tsarnaev, 19, was caught on Friday night (19Apr13) after a huge manhunt. His brother Tamerlan, also believed to have been a suspect, was killed in a shootout with cops.
