Well, over the weekend, Boston one-upped everybody. Neil Diamond himself was at Fenway Park in Boston to sing the song live (to the accompaniment of his recording). But the story is even nicer than that. Neil Diamond wasn't there before the Red Sox asked him -- he had been in Boston and called the team up on his own, and asked if they'd like him to come in and sing.
The appearance got a little bit of attention on the sports news on Saturday, but this is the full thing.
