Neil Diamond has written a new song paying homage to the city of Boston and the victims of the terrorist attack there.
The star, whose hit Sweet Caroline is played at every Red Sox home game, has been inspired by the tragic events last week which saw three people killed and more than 170 injured.
On Saturday, he made a surprising appearance at the first Fenway Park game since the marathon bombings to sing the song which has become an anthem of defiance in the face of terror.

The 72-year-old told Rolling Stone that the string of recent atrocities in the U.S. had moved him to write new material.
'I'm writing now and obviously affected by this situation in Boston, so I'm writing about it just to express myself,' he said.

Although he himself is from New York, the veteran rock 'n' roller has been associated with Boston since the tradition of playing Sweet Caroline in the eighth inning of baseball games in the city started in 1997.
Mr Diamond said that the Boston bombing was just the latest in a series of horrific events, such as the Sandy Hook shooting, which had spurred him to make music once again.

'It's like an infestation, and I'm writing about the general situation, not just about this bombing in Boston, but what we're going through with all of these tragedies - shootings and so on and so forth,' he said.
It is unclear when the song, which does not yet have a title, will be released.
However, the musician has wasted no time in recording his composition.

'I spent the whole day recording it and I will spend tomorrow recording it,' he told Rolling Stone last week.
'With a little bit of help from the man upstairs, I'll have it finished by the weekend.'
Mr Diamond, a member of the Rock and Roll Hall of Fame, has sold more than 125million records over his 50-year career.
His last album of all-new material was 2008's Home Before Dark, produced by Rick Rubin.
