The band U.S. Beat performed "Crazy" by Pat Green for the couple's first dance, followed by tunes by Michael Jackson, Lady Gaga, Frank Sinatra, and James Taylor. At one point in the evening, a circle of guests formed around the couple as they tried out a few impromptu dance moves. "People wouldn't leave the dance floor," says Katie. "It was packed from the time the band started to play till the time they kicked us out!"
