President Barack Obama spent his first night in what he calls the new era of responsibility being serenaded by some of the most famous singers of our time.

Beyonce crooned a classic to the new president, Sheryl Crow sang her famous song celebrating change and Diana Ross sang her hit I'm coming out at the Neighborhood ball, the first of ten balls.

First of all, how good looking is my wife? Obama asked the crowd when first introduced by Denzel Washington.

I want to thank all of you, not merely for helping me get elected, but I want to thank each and every one of you and all the people watching tonight for what you do to make this country better, he said.

Beyonce sang Etta James' At Last at the first ball of the night as part of a star-studded lineup that aired on ABC. It was the first song that the first couple danced to.

After the couple danced, the crowd started to chant Obama! Obama! Obama!
