It was a long week for the people of Boston. From the terror of the Boston Marathon bombing to the literal lockdown of a large part of the city due to a suspect on the loose, Saturday was the time to let it all go. And a very special guest at the Red Sox game made it all the better.

Neil Diamond’s “Sweet Caroline” is the song most closely associated with the Boston Red Sox, and the man himself made a special appearance at the game on Saturday. Diamond flew in from California – unannounced and at his own expense, according to Yahoo Sports. He led the crowd of over 35,000 at Fenway Park in a special rendition of the famous song.

All week, other stadiums across the country (even Yankee Stadium) have played the song as a tribute to the city of Boston. In fact, Yankee Stadium sported a banner of support for the city under siege.

While not a perfect performance, it was definitely the feel-good moment of the weekend. Watch Diamond’s performance with the fans from MLB.com via Yahoo Sports.
