Bostonians on Saturday were exhilarated with relief at the news that the deadly marathon bomber that put their city on lockdown was finally captured. In true American style, the town celebrated getting back to normal with a good ol' Red Sox baseball game--as well as a surprise performance from another national treasure, Neil Diamond.

The legendary entertainer flew into Boston and worked up the idea all of his own accord, asking if he could serenade Fenway Park with a live performance of his classic "Sweet Caroline"--which is the unofficial anthem of the team and played during every home-game eighth inning since 2002.

The enthusiastic crowd of 35,000 burst into roars of approval when the 72-year-old Diamond walked out on the field sporting a Boston baseball cap.

"What an honor it is for me to be here today!" answered Diamond. "I bring love from the whole country."

What followed was a buoyant sing-a-long fest, with the smiling Fenway Faithful dancing, waving American flags, and chanting "U.S.A! U.S.A!"

To top off the afternoon, the Red Sox won their game against the Kansas City Royals, 4-3.

In solidarity with Boston, "Sweet Caroline" was blasted in ballparks across the nation over the weekend. The song was even played and sang in Red Sox archenemy territory, Yankee Stadium.
