Billy Joel first played Madison Square Garden in New York City in 1978. Since then, helped by a once a month residency at the Garden, Billy Joel has now played 100 shows at the Garden.
Last night was the 100th show and Bruce Springsteen showed up to join in the celebration. Bruce congratulated Billy on his achievement. Then the two did the Springsteen songs, "10th Ave Freezeout" and "Born to Run."
Here's the moment.
