On the 3rd Play of Christmas... the band came out on the field! The Play is maybe the most famous sports play of all time. It happened in the Stanford v Cal game in 1982.
The Play refers to a last-second kickoff return during a college football game between the University of California Golden
Bears and the Stanford Cardinal on Saturday, November 20, 1982. Given the circumstances and rivalry, the wild game that preceded it, the very unusual way in which The Play unfolded, and its lingering aftermath on players and fans, it is recognized as one of the most memorable plays in college football history and among the most memorable in American sports.
After Stanford had taken a 20–19 lead on a field goal with four seconds left in the game, the Golden Bears used five lateral passes on the ensuing kickoff return to score the winning touchdown and earn a disputed 25–20 victory. Members of the Stanford Band had come onto the field midway through the return, believing that the game was over, which added to the ensuing confusion and folklore. There remains disagreement over the legality of two of the laterals, adding to the passion surrounding the traditional rivalry of the annual "Big Game."
